I am hoping that you can all give us some wise tips. We have an American Eskimo (Bella) that we have had for 12 yrs. Got her at ten weeks old. She has always been an only house dog. We all love her very much and she has always been wonderful. A week ago we got a new puppy. She is a Shih Tzu (Phoebe). Now Phoebe just has been a wonderful blessing. However, Bella is having a really hard time excepting the pup. Phoebe tries soo hard to make friends, but Bella just wants to not be bothered by her. She growls at her. Phoebe just get heartbroken. Bella has not hurt the pup, but gets very touchy when ever the pup goes near her or her things. We love them both so much, and I know age a breed has some to do with it. Any advice on how we should approach this issue?
