I've been wondering this for a while. Willow needs monthly dentals and I wonder if he associates going to vet with pain or the fact that when he comes home he can eat well and without having trouble. Does he understand that he's going to the vet so that we can help him?? I know it's difficult to answer since we never know what they are thinking but when he's back home after he seems so much happier and more lively. I hope understands that we are trying to help him.
