We puppysit our daughters Chorki, and we have an old Cairn terrier,Matti, and a Chinese, 3 years old, Sassi. Well Shelby and Sassi go nuts running and playing, but Matti would just as soon the pup left her alone. It's like, I did my time with Sassi, it's your turn now. Well, Shelby has learned not to jump in Matti's face, but now she will keep going to her and giving her gentle kisses. Matti lets her and it is so cute to see.
