are you saying big dog referring to your 7 lb shih tzu?? I have 4 dogs inside, the smallest is my 5 lb yorkie, the biggest is my 13-14 lb yorkie, and I have a shih tzu(10 lbs) and a biewer 6 lbs..I also have a german shepherd and golden retriever outside...the little yorkie always goes over to the dog run and licks the 2 big dogs through the holes...I don't think either one of my big dogs would nip at any of the other ones, but, I don't let them out together, as I'm afraid if the big ones got playing with the little ones, they could accidentally hurt them |
