Pure white Bull Terriers are allowed to carry markings around the head due to breed standard (AKC), but not at the body. Sometimes there are specimen seen all white with markings all over the body and not only limited to the head. These markings often show on the back and are therefore named “Saddleback Markings”. If your Bull Terrier is just a pet, healthy and not intended either for use as a show dog or breeding, this is acceptable. Except the “breeder” who sold you the puppy claimed to breed after Kennel Club standards and requested a lot of money for the pup. Because this was definitely not the case!
Why is that important at all? It is, in fact, for every Bull Terrier and for you as the owner. Because a constantly sick and suffering dog can cost you thousands in vet bills over the years. And saddleback markings – believe it or not, can be part of the problem. The breed is prone to some genetic health issues, which can be either minimized by correct breeding or made worse by incorrect crossings. If you don’t believe this, just study the Mendelian rules of genomics. A responsible breeder will always strive to create healthy puppies with stable genetics as far as he can influence this. Therefore he will only cross certain dogs after strict rules. Hence, his puppies will not present saddleback markings, because these only occur in incorrect breeding. That again causes a higher risk of genetic health predispositions. Pigmentation of the SKIN (NOT the coat) on the other hand is not unusual and not necessarily a sign of bad genetic disposition. In fact, Mila has such a LOT of dots on the skin all over her chest and belly, we sometimes call her “Dotty” for fun an wish to have $1000 for every one of her dots 🙂

Bull Terrier and Miniature Bull Terrier Breed Information: The Miniature Bull Terrier
The Miniature Bull Terrier was bred at some point to include the qualities and characteristics of the original English Bull Terrier in an even more compact size. Bull Terriers and Miniature Bull Terriers are not considered the same dog breed, but two different ones by some Kennel Clubs. But, except for the difference in size, both share the same character traits and appearance. Today in Bull Terriers and Miniature Bull Terriers both color variations – pure white and certain color combinations – are prevalent.
