My name is 2 year old dog!

He is a foundling. We have had him to a vet and he is healthy. Has have given him rabies and distemper/parvo vaccines. His fecal is negative. Probably 2 years old. He is 30 pounds and very friendly. Good with kids,other dogs and is house-trained and crate trained. He is super sweet and needs a person who wants to pet him and sit on the couch and snuggle. He was found in our neighborhood following my granddaughter home. Vet thought he was probably a bait dog and put out because he was not aggressive. Believe me he is not. He is a snuggle bunny. He looks to be a pittie mix. Please help! We have two other dogs, and we just cannot keep him. Needs someone who can snuggle him and teach him a few commands. He seems smart and again is just super sweet.
