My tinkerbell is 8weeks and almost 17lbs. We got her through a women who found mom and pups in a dumpster. I never seen mom, she found a home before I picked Tink up. At the vet last week the dr says he is positive she is a bullmastiff. I am lucky to have found this forum, and I have quite a bit if pictures on my profile of Tink and her brother and sisters (only 4 pups survived, I'm not sure how many there was though.) let me know what you all think she looks like.. I'm curious if the vet was right, she looks like it to me too from pics I've seen, but I just don't know!
