I have the vet come once a year to check the donks. He does a "Coggins" test, and that's about it.

Since the donks don't get shoed, I don't call a ferrier in. I normally just use a rasp to keep their hooves shaped. When the donks are active they don't need much hoof work. In the Spring, when the ground is softer and there's lot's of grass growing they do tend to get long pretty fast and I've had to learn to clip them before filing them, if I wait too long to get to them.

I generally give them a nice long brushing afterwards. They have limited patience with me working on their hooves, but will stand there and let me brush them for as long as I can stand it. I don't even use a halter when I'm just brushing them, the two of them come over and wrestle to be first in line for that.
