Adorable puppy in Center Moriches, New York

Adorable puppy for sale! Around a year old. His name is Havoc. I'm not sure his exact breed. I adopted him from a shelter that rescued him from Puerto Rico. He's a Lab-Pitt mix, we know that for sure. Some people say German Shepard too. He's sorta small though, I think. He's a loving dog. He IS a puppy and still needs training. He is potty trained, and still has chewing problems. I have been told because of the Lab mix, that's why. He nips when he plays sometimes, but he doesn't understand not to yet. He doesn't nip me, but my cousin when they play. If he is shown a lot of love and training he will be just fine. I let him lay in my bed and he licks me for about ten minutes until he curls up under my arm and falls asleep. Such a sweet dog. He understands the command "no" (when he wants to) and the command "sit", when he wants to. I am 18, and have a genetic disease. I just found out I might need a surgery and won't be able to take care of him. I have some toys, some tricks, and food/treats. I also have a cage(2 door), and blankets, and a bed to stick somewhere. I love this dog more then anything. This is really hard to do. I come from a family of like 4 dogs. I'm giving him up because it's what HE needs, not me. The last thing I would do is be selfish with this dog. I want to meet whoever wants Havoc, and make sure he likes them. Meet a couple of times and make sure he gets along with everyone. Thank you.
