YES. A million times yes. Those things are amazing. They actually make one specifically for horses, the blade is just wider, I think. I used one of the yellow dog ones until I lent it to someone and left it in reach of their horse after they LEFT and decided she wanted to play with it, and completely stomped it and destroyed it. Yeah... that's safe. I don't talk to that person anymore! lolI haven't tried this yet but I may, how do you think the furminator (the dog brush) would work during maulting season. I've got a million dogs and tons of furminators.
Anyway, with the furminator = amazing for shedding.
