I have recently purchased a golden Retreiver puppy, she is currently 10 weeks old and it is all ready clear she is going to be an extremely well behaved family dog. The problem I am having is with my 4 yr old neutered shihtzu, he is not adapting well to the new puppy. Anytime the puppy is within any proximity of the male he goes nut barking, nipping, growling to the point he will not calm down and has nipped at my wife and kids. I really do not know what to do any advice?
Thanks
