Situation: theres this horse, bear, that I help this lady, pat, take care of. Bear hasnt been doing too well the past month or so, first he had rain rot, and had that during the beginning on winter, so we separated him, he usually sleeps in the same spot, all the time, laying down, and it just so happens that its in his hay. Now he is missing blotches of hair near his front shoulder area and it appears to be spreading, but its hard to tell with his winter coat, the one major spot by his shoulder is about 6 inches round and completely bare now. The biggest problem though, is that he's not gaining weight at all, he eats 6 flakes of regular 2nd cutting hay each day and about 8cups of grain, and he's extremely skinny. Pat has wormed him, that's not the problem, she's ruled out all other problems, teeth, farrier, and she believes its that he is alergic to himself, she's had another horse like this before and that was the case, but the other horse wasnt loosing weight. She's planning on putting him down on wednesday, and for some reason I really don't think she should put him down, theres only a few more weeks till it really warms up and the snow melts, and I think that he can make it to spring then be fine, but I think I can help him. He was born messed up and deformed, he toes out in the front and is cow hocked in the back, and is a 13.1 hh morgan gelding, pat's had him for about 5 years, he's around 12, and his mother was sick when he was born and she wasnt expected to make it and he wasnt expected to be born, but he was, and his mom lived, and all was well, but his manure is larger then pony sized, so pat believes that his intestines and all are horse size and its jsut starting to catch up to him. So today pat told me she's going to have the vet look at him when she comes out to give some of the mares some shots, and she was planning on having him put down because it would be expensive to spend money seeing whats wrong through surgery, so I plan on going and spending the day with him tomorrow, and hopefully convincing her not to put him down for a while because he's still happy and alert. So I was sittin here looking through some recent pictures of him, and it kinda hit me, maybe he got sick from eating the hay with the rain rot on it? Is that possible?
