Maybe Cushings? Maybe something else?
My pony Bart is around 20 years old. We think he is a shetland/quarter pony mix. I've had him since he was 12 and I was 8, so yea, he is 20. Anyways, a few years back a vet had mentioned that he might have been in the early stages of cushings but then he never mentioned it again so we passed the idea off. However lately the symptoms have been seeming more and more fitting. In the past four months he has been losing weight and muscle. He has always had a long shaggy coat (which is why we think he may be part shetland) but he has always been shedding it off at odd times too. And last year he had a major hoof abcess that left him on stall rest for 2 months because it wouldnt break. And those are some symptoms of cushings disease which have been making me crazy lately. (I haven't noticed a huge thirst though) We have a vet coming out sometime this week to check him out and get him started on meds if he needs them. But a few days ago my aunt mentioned something I hadn't thought about, we changed our hay from teff to bermuda about four or five months ago. According to our farrier, the new hay has helped his hooves grow better and he seems to like it just the same.
So heres the questions, can a change in feed cause these symptoms too? Do you think its cushings? What else could it be? What should I ask the vet?
Sorry for the novel, any responses are much appreciated!
