Ken is 6 months old. He came in with his sister as a stray. Ken is the shyer of the 2 and relies on Barbie to open up. He has never been on a leash and we are working on that with him. He is better with another dog in the home, a confident dog. He is going to need a patient family to allow him time to adjust. A fenced yard is preferred as he is not leash trained yet.
