Jill, you are lucky. We have a good vet around here but only because the mini owners in the area insisted on her "learning" a few things. When she first started treating my animals, I swear, she could not understand why I would want be concerned about examining their teeth every year or have sheaths cleaned. She was terrible for floating (still lacking there) and popping off caps, "who does that?".
As for a physical, she listens to the heart, takes their temp, looks to see if they have a runny nose and then they're "good". She has a backyard mini and wanted to treat them as cute pets that you do as little as possible for. She's a good vet just not into treating them as if they were "real" horses or maybe I should say she not into treating show horses.
