I have four dachshunds. The two youngest, Karsten 2 1/2 and King 2 have played together since King has been there. King is blind and deaf. Karsten would initiate playing by bumping King. Apparently King got tired of it and about two weeks ago lit into Karsten. Karsten went in his kennel and stayed for about two hours. He eventually came out and everything seemed to be ok. About three days later, when King would just get near Karsten, Karsten would jump on him. They were getting into the worst, heart stopping fights. It was absolutely horrible. I've since taken Karsten to my son's house (since King is blind and deaf and is used to my house). I do not want to re-home either of them. I love them both, Someone with any ideas, please help. Thanks.
