[Dozer-Digger]

Last year I took my two to the vet for their shots, Dozer's second, and Digger's first. They knew just where to go, before I could even closed the car door, they ran up to the vets door wanting to go in. They were on retractable leashes, but I didn't need them. Dozer even started to scratch at the door.
Everyone outside never saw 2 dogs wanting to see the vet so bad. I think it has to do with their noses, they could smell that other animals went in there.
