One of the horses boarded at my farm has some odd symptoms and we can't pinpoint what it is. We are waiting on bloodwork back from the vet. He is around 28 years old and is a QH that has been pleasure ridden. A few years ago he was bought from Texas and moved to Chicago. The beginning of this college semester he was moved to my farm. in KY He came a little underweight and we have been very successfull at getting him to a great weight and he has held that weight. When he came he wasn't always eating his senior feed, but ate almost all. Some days he would eat most and others he would leave almost all of his grain. We switched him to Safe Choice thinking another grain would fix the problem. It didn't. Same issues. So we now put an oz of corn oil in for some flavor and 1/3 scoop beet pulp. He gets 3/4 scoop Safe choice as well. In the evening he gets his SmartPak which includes Condrogin EQ. Over winter break he began to really eat most of his grain and it was a relief. A week ago he has began to refuse to eat hardly any of his grain, not much hay, wasn't drinking, and has been seperating himself from the herd. Even though he isn't eating he has not dropped any weight surprisingly. Because he isn't moving hardly any when out to pasture his legs are stocked up so we hand walk him to reduce swelling. He gets 1/2 tube electrolytes per day and the vet found a little gengivitis in one tooth(not enough to cause this much of a problem and he has had regular floating) so he is also getting 2 scoops of Uniprim per day. Since he doesn't eat his food we are making a paste with the medicine and giving it to him in a syringe. This is the point we are currently at and we are puzzled. Any ideas??? Everyone at the barn is upset and doesn't know how much longer this horse has. Please help.
