What is the baby saying

More: King is a 2 year old Shepherd that has been rehomed 3 times, his original owner had cancer and was crating him all the in time until his hips started to fail. A neighbor took him but couldn't keep him because his dog was jealous. I now have him and tell him all the time that he is has a home now. He was not socialized sand didn't know how to walk on a leash. I hired a trainer and he is work in progress. He is so sweet!!
