Inbreeding in pit bull dogs
Pedigree Dogs Exposed is a BBC investigative documentary, produced by Jemima Harrison, which focused on the health and welfare issues facing pedigree dogs in the United Kingdom. It was originally broadcast on August 19, 2008 in that country.
The Kennel Club (KC), the governing body for purebred dogs in the UK that organizes the most prestigious dog show Crufts, was severely criticized for allowing dog standards that force animals to be judged solely on the basis of them, which generates breeding practices that compromise the health of pedigree dogs. The program traced the historical curve of pedigree dog health and welfare in the UK. The KC was also criticized by the Kennel Club (KC), the governing body for purebred dogs in the UK that organizes the most prestigious dog show Crufts.
The program traced the historical curve from KC to the eugenics movement, on which purebred dog breeding is based. A rhodesian ridgeback breeder interviewed during the program condoned the killing of healthy uncrested puppies because the breed standards prohibit uncrested dogs. The President of the Rhodesian Ridgeback Club stated that he considered the uncrested dogs to be genetically flawed. It should be noted that one in twenty puppies is born without a crest, so there is a section in the Rhodesian Ridgeback Club’s code of ethics that states, “Puppies without a crest will be euthanized.” The crest is a generic trait whose presence is said to make the dog more prone to dermoid sinus.
Advantages of inbreeding
It is a short and massive dog with a square and compact appearance, well proportioned and muscular; the large, rounded and solid-looking head is covered with folds; the muzzle is square and flat; the eyes are large and dark; it has straight legs and a curly tail. The fur is tight, soft and shiny. They do not know how to swim.
The pug can be of fawn color with its two variants: silver or soft apricot with a black mask, in both cases it has a black stripe that goes from the head to the tail, as it can also be pure black. There are litters of different colors not recognized by the breed standard, which can be brindle, white being one of the most common. Other variants have been seen but to a lesser extent.
Pugs, if well trained and properly socialized, are not aggressive animals. Like any dog, they can bite, but it is rare for this to happen without anyone mistreating the animal. They even get along very well with dogs of larger breeds than themselves.
Inbreeding dogs consequences
A criticism that seems to be in line with the finding made by a new study led by the University of California Davis, which has been published in the journal Canine Medicine and Genetics.
In the study, veterinary geneticist Danika Bannasch demonstrates that most dog breeds are highly inbred (specimens are too closely related), which contributes to increased veterinary care costs due to inbreeding-related diseases. “It’s amazing how inbreeding seems to be important for health,” Bannasch asserts.
The average inbreeding based on genetic analysis in 227 breeds was close to 25%, or the equivalent of sharing the same genetic material with a full sibling. These are levels that are considered well above what would be safe for humans or wild animal populations. In humans, high levels of inbreeding (3-6%) have been associated with a higher prevalence of complex diseases as well as other conditions.

Some breeds have experienced passing fads related to social phenomena: the long-haired Collie (Lassie), the German Shepherd (Rin tin tin), the Dalmatian (The 101). Now it is the turn of the French Bulldog, almost more numerous than pigeons.
The breeder interested only in profit produces litter after litter, forcing the bitch to give birth incessantly and without worrying about inbreeding or any disease transmissible to the offspring.
The British Kennel Club, the world’s oldest dog breed selection and standardization organization, has recently declared that “every dog should be able to see, breathe and move without discomfort or pain”. This is a positive step towards the abandonment of aesthetic extremism to the detriment of health. The evaluation criteria for dog shows, in fact, influence market demand, to which breeders have to adapt if they want to win.
The former are fearful animals, poorly balanced, afflicted by physical problems such as hip dysplasia. The latter have maintained their prerogatives, both mental and physical, but are considered ‘ugly’ and their extraordinary energy cannot be satisfied with a walk in the neighborhood.
