Good looking dog. Definitely Has either staffordshire or bully in the mix or possibly both.
APBT are not designated by nose color FYI. They are designated by coat color and typically Pits have to be crossed with a staffy to achieve the “blue gene”.
My two APBTs. Colbys been in my family for over 100 years. These two boys come from a long line of working dogs.
White with brindle is Diggy
All brindle is Mojo
