It is believed that Rottweilers descended from the dogs of Roman legionnaires, which soldiers used to guard livestock. These are large dogs with a balanced constitution - they are not overweight, but not lean either.
The height of males is about 62-68 cm at the withers, and females are slightly smaller - 55-63 cm. Rottweilers weigh in the range of 40-50 kg.
Representatives of this breed can have only one color – black with red tan. Rottweilers are not whimsical, and they do not require special conditions.
These are serious, balanced dogs, they are courageous and self-confident, so they should be owned by people with the same character.
If the animal is raised correctly, it will not show aggression, however, if the puppy is not raised, it can grow up aggressive and even dangerous to its owners.
Rottweilers are very loyal to their owners and always reciprocate love and good treatment. They are ready to guard their home and owners around the clock.
The concept of "mestizo"
In any breeding, the main type of crossing is purebred. The addition of other blood is permissible only in rare cases. But sometimes there is a need to get a dog that combines the characteristics of two breeds.
The breed was named Malkhover
The most striking examples:
- The Caucasian Shepherd was crossed with the Saint Bernard. As a result, we managed to get a Moscow guard dog that had the appearance of a St. Bernard and the character of a Caucasian Shepherd.
- The mixed breed of Alabai and Rottweiler was distinguished by a strong physique, powerful muscles and thick hair. These dogs were perfect for home guarding.
- The Pitweiler is a mix of Pitbull and Rottweiler. Such pets are distinguished by fearlessness, endurance, and energy. The hybrid requires seriousness from the owner, since without constant training he goes crazy.
- Sometimes you can find a cross between a mongrel and a Rottweiler. This combination is unpredictable. Such a dog can be unbalanced and aggressive.
Crossbreeding is very risky, as you can never be sure what qualities will be passed on to the litter. Hybrids may be healthier. Some small breeds have many problems due to close relationships.
Interesting! Infusion of other blood can correct the defects. However, such work should be done by experienced breeders.
Healthy dog with an unpredictable character
It is believed that mestizos take the best from their parents, and this opinion is not groundless. Hybrids often have good health, since they do not inherit genetic diseases from their ancestors. But this does not mean that the mixed breed will never get sick, because poor living conditions can undermine any dog’s immunity.
The character of hybrids may not be as good as their health. There is a fifty-fifty chance that crossing two different breeds can either balance out negative traits or enhance them.
Take, for example, a cross between a Rottweiler and a Caucasian Shepherd. Both breeds have a dominant character and are capable of showing aggression. Two options are possible: either absolute calm (naturally, when the owner and his family are safe), or a redoubled desire to be a leader and sudden outbursts of anger towards strangers. In any case, such a mestizo needs a firm hand from the owner and constant training.
But if you cross a Rottweiler with an American Bulldog, then there is a risk of getting an explosive mixture of activity and viciousness. And although breeders managed to reduce as much as possible the aggression and pursuit instinct in bulldogs, they remained at the genetic level. However, the dog can be as lazy as a Rottweiler.
Don't forget about the sizes. No one can give a 100% guarantee that a tiny puppy will not turn into a huge bear. A mixed breed of Rottweiler and Central Asian Shepherd Dog (Alabai) can grow to the size of a Rottweiler and weigh about 50 kilograms. Or it can reach 70-100 kilograms, because the Alabai is one of the largest dogs in the world.
The same results can be expected when crossing a Rottweiler with a Tibetan Mastiff, St. Bernard or other large breeds. The size of a puppy's paws can indicate the dog's future size, but it is not an exact measurement.
Among fans of hybridization, there is an opinion that the participation of a Rottweiler in crossing can produce a mixed breed similar to the American Pit Bull Terrier. That is, the dog may have good nature, loyalty to the environment, stubbornness, endurance, a desire to reach the end, activity controlled by aggression.
A little history
A cross between a husky and a shepherd dog: a description of mestizos
A cross between a Rottweiler and a German Shepherd appeared in the mid-20th century. The breed is considered young and still little known throughout the world. Germany became her homeland. A group of Germans set out to get new dogs with a stable psyche and balanced character. Particular attention was paid to the level of health.
The best representatives of the breeds were selected for the work. The first mixed breeds of Rottweilers and German Shepherds definitely pleased the breeders. Hybrids were distinguished by high trainability, obedience, and good health.
Further crossing allowed only the best qualities to be consolidated in the new breed. Therefore, the breeders decided to present the Rottweiler-Shepherd mix to the professional canine society.
Rottweiler and Shepherd
However, experts refused to recognize the new breed. In their opinion, mestizos do not have a stable set of characteristics, and the results of selection are not yet permanent. At this stage, the targeted work on breeding a new breed ended.
Interesting! Some dog breeders make their own hybrids and sell puppies.
The Rottweiler-Shepherd mix is considered to be versatile and has excellent working qualities. This breed is popularly called Malkhover, and it is popular among connoisseurs of unusual dogs.
Dog breed German Shepherd
History of the formation of the breed
At the end of the last century, the German Shepherd was a relatively unpopular herding dog, used in different regions of Germany to herd sheep. In northern and central Germany it was of the squat, massive type, and in southern Germany, mainly in the Württemberg region, a lighter, tall-legged type was bred.
By crossing both of these varieties, the modern German Shepherd was developed. Its triumphal march around the world occurred after the outstanding, wonderful properties of this service dog were established.
Soon after this, it became a popular breed, which, with its abilities for various training, the beauty of its forms and other valuable properties, especially its sensitivity and devotion to its owner, won the sympathy of dog breeders around the world.
The great happiness for this breed of dogs was that the outstanding dog handlers of that time categorically insisted that its breeding should not be focused only on the cultivation of exterior forms, but should be based on performance indicators, which was constantly emphasized in the instructions for breeding this breed. This kept the breed at the proper level and even increased its popularity.
Because of its resemblance to a wolf, the German Shepherd is popularly called the “wolfdog”. However, this does not mean at all that, in addition to its ancient ancestors, it has something in common with the wolf. True, many experiments have already been carried out by crossing it with a wolf in order to give it properties typical of a wolf - tirelessness during long trotting, etc.
Unfortunately, the crossbreeds and their immediate descendants simultaneously inherited those properties that are inherent in the wolf and reduce the value of the German Shepherd, such as cunning, cowardice, intractability to training, poor obedience to humans, etc.
Popularity in the world
The German Shepherd is one of the most popular and widespread dog breeds in the world. In recent years, in Europe the number and breeding of this breed has been very carefully controlled. In its homeland, Germany, the breed, together with dachshunds, is at the peak of both numbers and popularity.
With its roots in Thuringia and Württemberg, the shepherd dog enjoys the boundless respect of dog breeders in Germany, despite this, in neighboring France there are about 300-hundred thousand dogs of this breed, which provides it with third place in the popularity ranking. In the United States of America, only the poodle is ahead of the “Germans” in terms of popularity. Since in the USA, the shepherd is considered a “military” and “service” dog, its popularity, as well as its numbers there, is increasing every year.
In organizational terms, all national unions of German dog lovers are united into the International Union of Dog Lovers of this breed.
The main inspirer and organizer of the creation of the German Shepherd Breeding Society is the Prussian knightly master, Baron Max von Stephanitz, who in 1899 founded the German Shepherd Union in Karlsruhe. This union subsequently determined the main selection criteria for the breeding and development of the breed. Thanks to all this, it is much easier to identify an individual dog of a given breed that has breed defects than to detect defects in dogs of other breeds.
Currently, the breeding of this breed is carried out in a pure manner and is based on careful selection and selection of the best animals in terms of appearance and service qualities. In our country, the German Shepherd is very popular and is one of the most common breeds. The principles of her breeding are the same as those of dog breeders in her homeland; selection and selection during breeding, first of all, is based on service qualities. Which are tested not only in tests, but also in daily work in the search service, when protecting state borders, accompanying the blind and in many other human services, in which she shows her abilities and quick adaptability. In connection with all this, we should not fear for the fate of this beautiful breed, even in the current time of dynamic technical progress.
Detailed description
It is difficult to accurately characterize a mixture, since puppies inherit traits from both parents. What they will have in common is large size, proportionate body, muscularity.
External data
Cross between German Shepherd and Caucasian Shepherd
Malchover is a dog that is more similar to a Rottweiler. The dog has a toned, slender body, a wide chest and a straight back. The paws are very long and thin.
The Rottweiler/Shepherd mix has more characteristics of the former breed. The Malchover's head is medium in size with a convex forehead, with a noticeable occipital protuberance. The muzzle narrows towards the nose.
The nose is large, black with large nostrils. The jaws should be equal in length and have a scissor bite. The ears are drooping and triangular in shape. The tail is long and straight.
The Malchover has a hard, short and coarse coat. The most common color is black with tan markings on the paws and belly.
Interesting fact! The cross between a Rottweiler and a German Shepherd looks impressive. Therefore, such dogs are used to guard the territory and protect the owner.
Males reach a height of 70 cm at the withers, females 65 cm. The average weight of an individual is 50 kg. Such pets are not suitable for apartment living. Therefore, it is better to keep Malchover outside or in an enclosure.
Types of "Germans"
Representatives of this breed can be short-haired or long-haired. In the first species the coat is thick and hard, on the tail, neck and hind legs it is softer and longer, the undercoat lies tightly to the body, in the second the coat is long, soft, slightly wavy, the undercoat is weakly expressed.
Also, German Shepherds are divided into types according to the breeding line:
- exhibition - purebred individuals with an exterior as close as possible to the standard;
- working – have a denser and squat build;
- Shepherd dogs of East Germany are heavy, strong dogs with a massive body and a large head;
- American – these dogs are taller than their German relatives and have an angular build;
- Czech – outwardly they look like shepherd dogs from East Germany, but have a more docile and calm character;
- Belarusian Shepherds are strong and hardy dogs with dark or spotted hair, obtained by crossing German and Central Asian Shepherds and Russian Laikas;
- British - they are characterized by a long, stocky body and short legs.
In addition, as a result of breeding work on crossing German shepherds with other animals, such breed varieties as the Czech Wolfhound, American Shilohound, Dutch Sarlouz Wulfhound, and English Utonogan were obtained.
Features of behavior
A cross between a husky and a husky: name of the breed, appearance
Both the Rottweiler and the German Shepherd have complex personalities. Dogs of these breeds require constant training with the owner and supervision by a dog handler. The dogs are trained not only in general training, but also in protective guard duty.
Malchover has absorbed the qualities of both parents
Rottweilers are fearless, self-confident and have a balanced character. A dog of this breed will perfectly guard the territory.
German Shepherds are more focused on cooperation with humans. This breed can be called one of the most important among service dogs. The dog will be pliable and easy to train.
Malkhover absorbed the character of both parents. The crossbreed has a high level of intelligence, obedience and intelligence. The puppy will demonstrate a balanced character.
Important! Negative qualities include obstinacy, pride and excessive independence.
At the same time, malchover shows activity and mobility. He will enjoy outdoor games, running and long walks. Metis will get real pleasure from joint activities.
The dog is very dependent on the owner and will suffer from long periods of loneliness. Therefore, malchover is not suitable for busy people. You need to constantly train your pet and spend long hours together.
Before purchasing a puppy, you need to compare different breeds, write down their pros and cons. This will give you an idea of each dog. You should not rush to conclusions, since the pet will live for at least 10 years and you need to approach its choice responsibly.
Malkhover is able to withstand any physical activity. You can use it for cross-country running, obstacle courses, agility and other active sports.
Malkhover is a serious dog; the description of the breed does not give a complete picture of its characteristics. Such a pet requires strictness from the owner. Metis has an obstinate and stubborn character, so it will be difficult for a beginner to cope with him.
Who to choose: Cane Corso or Rottweiler
Both of these breeds are generally similar, both are guard dogs, but the Cane Corso is more of a bodyguard, and the Rottweiler is more of a watchman. Cane Corsos are more active and need frequent long walks. Also, like Rottweilers, they are quite balanced. Training a Cane Corso is somewhat simpler than training a Rottweiler.
The disadvantages of the Cane Corso include::
- long-term shedding;
- excessive drooling, characteristic of this breed.
Thus, when choosing a dog, no matter whether it is a purebred Rottweiler, a mixed breed, or a dog of another breed, you should understand that this is a creature that has its own character and certain needs.
When getting a pet, you need to be aware of the full degree of responsibility, because how it will grow up depends, first of all, on the owner, on his attitude towards the dog, on proper training and upbringing.
Aggression on the part of dogs such as the Rottweiler is only the result of the wrong actions of their owners, insufficient attention and improper training.
Also read about how the choice of nickname affects the character of a Rottweiler.
Advantages and disadvantages
Each breed has its own pros and cons. Malhover's strength is its excellent protective and guarding abilities. Metis is distinguished by a high level of health, affection for the owner and other family members.
Such a dog will not bark for no reason and disturb the owner. With proper training, your pet will become an excellent friend and protector. Thanks to its endurance, a malkhover can accompany its person everywhere.
The hybrid does not whine or bark for no reason.
But the mixture also has negative sides:
- Aggressive attitude towards other pets, especially small ones. Therefore, you should not get a dog if there are already pets in the house.
- Intolerance towards children. The dog will not patiently tolerate the tricks of a child, especially if he is small. It needs to be isolated from the child or the puppy should not be taken into a family with children.
Due to the fact that the Rottweiler blood predominates in the crossbreed, Malchover can negatively perceive any guests. Instinct tells him to behave this way around strangers.
Another disadvantage of the hybrid is the difficulty of walking. Malhover needs to be taken out only on a leash and with a muzzle; he can only be released in the forest where there are no people. In other cases, you will have to limit your pet’s movements.
It is advisable to work with the dog under the supervision of a dog handler. He will show you how to teach different commands and suggest solutions to difficult situations. This is especially important for those who have little experience communicating with animals.
Training begins from the first month of the puppy’s life
With proper upbringing, Malkhover will become a devoted friend. He becomes nervous and aggressive towards people only when there is a lack of communication.
German Shepherd – the standard of devotion
The ranking of the most loyal dogs is opened by the German Shepherd, whose ancestors are considered to be wolves of the Bronze Age. The first breeder of this breed was Captain von Stefanitz, and the world learned about the German Shepherd in 1882, at the Hanover Exhibition. The main advantages of the dog are exceptional devotion, intelligence, courage, and good fighting qualities. In addition, it is a reliable guide for the blind, as well as a watchman and protector of the owner’s property. However, the dog’s character is not aggressive - if such traits do appear, this is rather a cost of upbringing.
Did you know that during World War II, German shepherds successfully “worked” as messengers, signalmen, orderlies and sappers? Many seriously wounded soldiers were able to survive only thanks to these four-legged heroes, who found and pulled them out of the battlefield.
Rules for choosing a puppy
In most cases, a hybrid is bred for official purposes, for example, home security. In this case, you need to carefully examine the litter and choose the bravest puppy.
To check, they use a simple test: they throw a bunch of keys in front of the kids and see who runs away and who doesn’t. A puppy who is not scared and comes up will do.
Another way to check is to observe the attitude towards a stranger. If the baby himself approaches the guest and smells him, then everything is fine. Malchover is an unrecognized breed, so metrics are not given for the puppy.
The owner can install a chip with personal information himself. The baby must be vaccinated according to schedule. Although in good health, he may suffer seriously from infections.
Important! The veterinarian knows what vaccinations to give. You must strictly follow his recommendations.
Before buying a puppy, it is advisable to look at its parents. From them you can get an idea of what the children will be like. You need to pay attention to the exterior and behavior.
What the puppy eats also matters. From the first days of his appearance in the house, he must be provided with a nutritious diet. The baby is fed 5-6 times a day (about 150 g serving), gradually reducing this amount to 2 times.
The basis of proper nutrition for Malkhover is raw meat and offal. For example, in one feeding they give 100 g of beef and 50 g of beef heart. Additionally, a raw chicken egg is poured into the meat.
Malchover is a German Shepherd-Rottweiler mix. This dog is suitable for home guarding, but it requires special treatment.
Diet of German Shepherds
As soon as you get a German Shepherd puppy, you should make sure that its diet is balanced. At first, you need to feed the baby the same food that the breeder treated him to, gradually expanding his menu. The metabolism of puppies is more intense than that of mature four-legged animals, so they should be given food in small portions, but much more often.
The number of meals is directly related to the age of the pet:
- At two months of age, six meals a day are fed;
- At six months of age, the dog begins to eat three to four times a day;
- Closer to ten months of age, the shepherd dog eats twice a day.
Dogs can eat specialized ready-made food or natural food. The main thing is that the food is balanced, rich in all essential vitamins, minerals and other nutrients. It is very useful to add milk and other dairy products, especially cottage cheese, to the diet of puppies. At two months of age, the menu includes 100 to 200 grams of raw meat, excluding pork. At the same time, puppies begin to be given cartilage, and then they are also fed boiled eggs, offal, and fish.
In order for the puppy to grow quickly, become stronger and fully develop, it must be provided with proper and healthy nutrition. This will protect him from various diseases and ailments, make the pet’s life happy and cloudless, and contacting a veterinarian will only occur as part of a routine preventive examination.
Breeding versus plain mating
It is fundamentally wrong to consider selection work to create a new breed and random or “for the sake of curiosity” mating as the same thing. To develop a new breed, breeders do a tremendous amount of work. Their goal is to consolidate the necessary mental qualities and physical characteristics in the breed through long and tough selection.
It was precisely these goals that the breeders from the former GDR pursued when crossing the Rottweiler and the German Shepherd. They wanted to breed a harmoniously built, hardy and mentally balanced dog, which is exactly what they achieved. The breed was called Malchover, but it never received official recognition.
However, fans of the Rottweiler-German Shepherd hybrid still exist. After all, such versatile dogs do an excellent job with protective, guard, search and security services. But, despite the loyalty, activity and obedience taken from the shepherd, mestizos have the stubbornness, aggression and dominance of Rottweilers. Therefore, to keep the dog under control, the owner must have leadership qualities.
Purpose of breeds
Of course, the German Shepherd and Rottweiler breeds are different from each other. These two dogs have one thing in common: they have working qualities and serve humans.
Purpose of the German Shepherd:
- She performs a service and guard function in the border troops,
- Used for detective work in the police during operational and anti-terrorism activities,
- Used by dog breeders to protect the house and property,
- Protects the owner and his family.
The purpose of the Rottweiler has the following variations:
- Used as a bodyguard to protect people,
- Used by the military to protect state borders,
- Can protect and guard the house, yard and all family members.
For inexperienced dog owners, it is preferable to use a German Shepherd for protection rather than a Rottweiler. It's all about the character and behavior of these pets. We'll talk about this a little later.
Basic moments
- Rottweilers reach full physical and psychological maturity by two years.
- They require long walks combined with active games and physical activity.
- They need a serious and strong mentor. They will create a lot of problems for inexperienced owners who do not have the skills to work with service dogs.
- Rottweilers do not tolerate high temperatures well, but they feel quite comfortable in the cold, thanks to their dense undercoat.
- They recognize the dominant role of the owner, but absolutely do not accept violence against themselves.
- They are smart, capable of making decisions with lightning speed if there is a threat to human life and health.
- They have a good appetite, thanks to which they are able to quickly “eat up” extra pounds and lose shape.
- They get along well with the pets they grew up with.
- Small dogs and puppies are treated with indifference and contempt. They sense rivals in large individuals, often provoking them into a fight.
- Animals that have not completed the mandatory training course are usually uncontrollable and pose a danger not only to others, but also to their own owner.
Rottweilers are serious and energetic brutal dogs, whose main purpose is to serve people. Rottweilers make the best rescuers and guides, ready at any moment to risk their own lives in the name of saving people. On the street, these muscular beauties are the epitome of menace and alertness. They are energetic, observant and always in control of the situation. However, as soon as the dog returns home, the affectionate sloth awakens inside him, occupying the soft sofa and ready to devour kilograms of treats.
How to feed?
Diet
With natural nutrition, the pet’s menu should consist of:
- lean meat;
- offal;
- eggs;
- cottage cheese;
- buckwheat, rice and barley porridge;
- vegetables and fruits.
You will also need to take additional vitamins and minerals.
You should not give Rottweilers:
- tubular bones;
- pork;
- pickles, smoked meats, seasonings;
- pasta and bakery products;
- potatoes and legumes;
- semolina;
- sweets;
- freshwater fish.
It is prohibited to feed dogs leftovers from the communal table.
Food must be warm. Feeding cold or too hot foods leads to the development of gastritis.
If we are talking about ready-made food, then it should be premium, super-premium or holistic.
The most popular brands of feed:
- Hill`s;
- Royal Canin;
- Eukanuba;
- Purina Pro Plan.
Due to the tendency of Rottweilers to overeat and become obese, it is necessary to adhere to a feeding schedule and control portion sizes and the number of calories consumed.
Interesting Facts
Germans are rightfully considered the No. 1 breed in the world. The following interesting facts are associated with these brave animals:
- Working German Shepherds have saved many people. In doing so, they often sacrifice their lives.
- Representatives of the breed reach maximum speed almost instantly. They do not lose their balance during sharp turns and never stumble.
- During the war, dogs worked as sappers, orderlies, messengers, and carried cartridges.
- The clamping force of the jaws during a bite exceeds 100 kg/cm².
- A powerful animal with a muscular body and dry bones is capable of speeds of up to 50 km/h.
- Several monuments have been erected to the Germans. One of them is located in Tolyatti - here a dog waited for its owners on the side of the road for 7 years.
Weight and height standards
The size of the German Shepherd allows it to be classified as a large breed. This category includes animals whose weight exceeds 25 kg and height reaches 60 cm.
The breed standard establishes the following physical parameters:
- height at withers for boys 60–65 cm, for girls 55–60 cm;
- average weight 30–40 kg and 22–32 kg, respectively.
The breed has pronounced sexual dimorphism. Males differ not only in weight and height at the withers, but also in physique - they are stronger and more massive than females. The difference is easy to see if you put a girl and a boy next to each other.
German Shepherds grow until they are 11–12 months old. But formation is completed only by 1.5–2 years.
The weight of an adult German Shepherd should not exceed the permissible limits. Excess pounds impair work performance and provoke the development of many diseases. Any deviation that affects performance characteristics is considered a serious defect.
Color and varieties
German Shepherds come in three colors - black and yellow, gray, black. However, within each suit there are many subtypes. According to the standard, none of the colors has advantages over the other. There is only one requirement – good pigmentation.
The most common is black and yellow. These are the dogs that appear in films and commercials. The back of the animal is covered with a V-shaped black mantle, covering the sides and top of the tail. The underparts are light - most often fawn, but can be brown or gray. There is always a black mask on the face.
Other colors of the German breed:
- plain black is one of the rarest colors. The shade of the coat is deep and rich. Particles of a different color are not acceptable;
- zonal gray - with a gray color there are dark spots on the back and a black mask on the face;
- zone-red - a red dog, like the zone-gray, has darkening on the back and a black mask on the face.
The White German Shepherd is outside the breed. She is characterized by an unstable character, timidity and timidity, and therefore is not suitable for performing official duties.
Depending on the structure of the coat, dogs are divided into two types:
- long-haired – the guard hairs are quite soft. Feathers form on the ears and limbs, and pants appear on the hips. The tail is bushy with a characteristic dewlap on the lower part;
- smooth-haired - thick, dense fur, with good undercoat. Slightly longer on neck, hips and tail. The hair does not puff up, but fits tightly to the body.
In Germany, only short-haired dogs are allowed to participate in exhibitions.
In 2010, German Longhairs were recognized as a separate breed. Previously, such animals were considered defective. Experts note that fluffy German Shepherds are overly excitable and nervous. Therefore, they are less often used as service dogs.
There are dwarf German shepherds. This is an unrecognized variety that resulted from a genetic glitch. The animals are not allowed to be bred, but some people keep them as pets.
Training allows testable combat
To consolidate various service qualities for working dogs, special test fights were invented. Also, combat tests allow you to find out which of the participants put up for battle is stronger, more savvy, more agile, and braver. During a fight, you can notice the advantages and disadvantages of a dog, which you may not know about in everyday life.
Test fights are events supervised by experienced keyologists, but in no case are officially prohibited bloody dog fights.
For each test fight there are strict sporting rules, violation of which leads to fines or disqualification of participants. Those who violate Article 245 of the Criminal Code of the Russian Federation (cruelty to animals) can expect fines, compulsory or correctional labor, or restriction of freedom for up to one year, or arrest for up to six months.
Down with stereotypes
In the past, dog fighting was a brutal, bloody spectacle used by breeders for profit. Some breeds were specially bred and then trained to participate in battles. Each owner of the future participant tried to get from him fearlessness and readiness to engage in battle with any opponent, sometimes until his last breath.
Cruel fun has sunk into oblivion; now open dog fighting is officially prohibited. But the “fighting dog” stereotype remains. Many people still believe that such dog breeds are uncontrollable, aggressive and ready to attack at any moment.
However, their opinion is wrong. Yes, initially the task of fighting breeds was to persecute their own kind. But not people. After all, before the fight, each participant calmly stood near the gathered crowd and endured the inspection of the judges monitoring the fairness of the fight. Naturally, such a past has left its mark - many dogs are genetically predisposed to varying degrees to show aggression.
But with proper upbringing and training, dogs will not show the evil side of their character unnecessarily. If the dog does not listen to the owner, shows excessive aggression, and rushes at passers-by, it means that the owner did not raise him well. Or specially trained.
In general, modern “fighters” are the owners of good physical shape, strict and, in most cases, balanced character. Now they are used only to serve humans.
