This is a hard concept for a Scottie. Sidney had all of the toys until Shelby came along and he learned that now he had no toys. With the advent of Sophie they have learned that Sophie will battle for all of the toys and she might allow the others to play with something. This little 5 lb. dog has taken over everything. She will play tug of war with Shelby and not give up. Sidney is smart enough to avoid this game. My daughter wanted to know if there was such a thing as shaken dog syndrome. Watching Sophie and Shelby play this afternoon gave rise to that question. We will be going to the vet tomorrow for her next puppy visit. I will make sure to ask the vet. They did share a bowl of water for the first time together. Rocky stayed out of the way of all of the activity.
