Band-aids for dogs??

Allie had her annual trip to the vet yesterday for her well-pet check-up. They had to draw some blood for a routine heartworm test and she came back to us wearing a band-aid. We'd never seen a band-aid on a dog before. We thought it looked pretty cute. I think there was something special in the shot they gave her because she woke up extra smart this morning. Within about 10 minutes, she FINALLY grasped the concepts of "shake" and "roll over." We've only been working on it for a year and a half! Now Allie's routine consists of "sit", "lay", "roll over", "shake", "wait", "up", and "catch".
