also - i think of myself as a responsible, experienced bully owner but there is one thing thats got me stumped!!
we saved buddy so know nothing of his pedigree and there is something thats bothering me...
his characteristics match the breed standard of a pitbull. he acts, dances, speaks, looks, eats like a pitbull

BUT he has a strange criss cross pattern on his tail??
does this mean somewhere along the lines another breed has snuck in? or is it a deformation? or is it a rare bloodline?
HELP please, i want to expand my knowledge on the breed so all comments considered and appreciated!
