A friend at the barn has an older mustang and he has been dropping weight pretty quick. They have upped his food and are going to worm him. His teeth were done 4 months ago and they are going to get them checked again. Is there anything else that they could try/check? I know they are going to have the vet out probably next week. They also were going to get beet pulp too.
I know he is a mustang and about 15 to 20 years old, but not much more than that.
