Hello. I just got my first horse and she has problems with choke, well the first time she did it, I did not know she has any problems and it scared me to death, anyway we got it under control now and know how to prevent it and everything. Since then, (about 2 months ago) she has been losing a little weight at first but now will not gain any. I just wanted to know what I should to do put weight back on her? She is a Thoroughbred mixed with Arabian, 19 years old, and about 15.5hh.
