need gone asap

not to sure how old he is but he’s still a puppy and he still has his baby teeth. He’s potty trained and doesn’t necessarily have to be on a leash to go. He HASNT been to the vet and got his shots but we’ve had him for maybe 5 months with one of our older dogs. he’s a inside puppy. doesn’t do great with other dogs (in my opinion) just because he’s always biting on our other one and trying to assert dominance but other then that he’s good. hes not fixed which may help with that. he does need to be taught manners (i.e. no biting, jumping) he knows how to sit, lay and to give his paws. he looks like a bluenose pit with some brindle in his coat but don’t have any papers to prove otherwise. he has two chew toys. he isn’t on special food but we always feed them Rachel Ray brand and give milk bone treats. he’s easier to shower with then to bathe outside but he does love playing in puddles and mud. oh yea his name is mudball and I’m having to give him away as I can’t take proper care of him anymore with me fixing to start college and moving.
