Oh my goodness! How adorable! I'm sure everyone will get alone just fine. When my Puddy was only 5 weeks old w/her leg in a cast, she was determined to join this family. After I kept her isolated for the required period, she realized that she loved our border collie Heidi who was 75 lbs. as opposed to Puddy who was 1 lb. I guess Puddy realized the discrepancy in weight and not to be outdone, she hopped on Heidi's back as if to say "Well then, you can be my chauffeur." And Heidi was so good natured about it except when Puddy insisted on playing w/her tail. Then she'd curl up her lip like Elvis. But she never growled or snapped. Given the right circumstances, they all can get along w/out danger.
