Here's why:
* "Pit bull" is not a breed: "Pit bull" is a general term used to describe dogs with a particular look and history. There are several breeds that fall under this umbrella term, including the American Pit Bull Terrier, American Staffordshire Terrier, and Staffordshire Bull Terrier.
* "Tiger stripe" refers to a coat pattern: The term "tiger stripe" refers to a specific coat pattern, often seen in dogs with brindle coloration. Brindle is a pattern with streaks or stripes of darker color on a lighter background, resembling a tiger's stripes.
* Coat patterns are not breed-specific: Brindle is a coat pattern that can appear in various breeds, not just those associated with the "pit bull" term.
Therefore, while a dog might have a tiger stripe coat pattern and be of a breed associated with "pit bulls," the term "tiger stripe pit bull" is not a specific bloodline or breed.
