It is my dog, i love it, i take care of it and i''m proud of it...but i just want your opinion about the breed, that's all.. i didn't say if it's not an original APTB i will get rid of it...is still my dog even if it is a chiwawa.. But thanks anyway...Without a pedigree you cannot tell. We can only make a guess but who cares? Call it a pit mix or a mutt. Love it , feed it ,train it and be proud of it. Along with being a responsible owner because even if it has no APBT in it if it looks similar to one then anything bad or good it does will represent the breed.
