I'm a novice horse owner. My miniature was recently diagnosed with heeves. He has had rounds of cortisone, climbuterol and is now on an antihistamine twice a day. He has a great appetite but almost constantly sounds as though he's trying to play a trumpet - badly. The vet's advice is to try to find him a home in a cooler climate or put him down when he becomes too uncomfortable. Neither choice is one I like and was wondering if anyone has advice on how to make life better for him. Thanks.
