I’d never be rubbing a heating gel on my horses cornet bands. If her diet is good maybe you just need to give it time before you see results. My horses hooves grow slow always have they get plenty of movement running on 180 acres. I only need trimmer out 3 to 4 times a year…that’s just fine with me. I’m not going to feed for faster hoof growth that’s for sure.
Both are barefoot sound on all surfaces,so why mess with what works for the horse.
