I had him at 6 weeks old one because some dumb idiot dumped him and his brothers and sisters in a box in a ditch. And two they were eating and drinking on their own at 6 weeks many puppies can be on there own at 6 weeks. When I first got him I was told they were unsure of his breed but I wanted to give him a home. As he got bigger I could tell he was a pit bull and theres no doubt about it. My Vet suggested I wait till he is 1yrs old to do the surgery he told me in bulldog breeds (pits, american and boxers.) Will not have a defined Masculinity if u neuter them too early. I plan on getting him neutered asap now that he is showing aggression issues. I was just listening to my vet.
