We just got my husbands heeling horse back from the vet. She had a guttural pouch infection and is now on a powder antibiotic after 2 day of intravenous antibiotics but the stubborn horse won't eat it and I am out of ideas. I've tried putting the dry powder on her grain, I've tried soaking the powder in water first then putting in on her grain but she's refusing to go any where near it! So any advice would be welcome.
