I have a horse that has a tooth abcess. Vet has given shot and a powdered medicine to put on his feed every day. Problem is he is not eating very well. Vet said we can mix in a syringe and give. What is the best thing to mix it with to get it down? Vet also said the only way to remove the tooth would be to cut hole from the outside and knock the tooth out. This sounds horrible to me. Hate to question the vet, but is he right? Thanks
