Thanks for the replies! Well, just wanted you to know I took Pancake back to the vet, she looked at her eyes and said they were fine. I'm not sure if they do wander when she is tugging on toys or if it just looks like it. The vet also said dogs could have wandering eyes just like humans do, but I've been looking closely at Pancake's and they seem okay. I think I was just being a little paranoid! New mommy, can't be too careful
