He’s so lucky to have you! It’s wonderful that he’s thriving now. You remind me of my son, he snatched a puppy from his neighbor because they left it alone with no food or water for days.Our vet is predicting anywhere from 90-100lbs. We had thought for a while that his growth would be stunted because he had a rough start. His previous owners were letting him die in their backyard. I got him and brought him to the vet,his intestines were folding into eachother, colon completely prolapsed, and had necrotic tissue on his small intestine. Lots of $$$ later and he's finally growing and thriving.
