It's been a while since I've been around. I have been soooo busy! I wanted to come pick y'alls brains on this one, because around my barn we are all wondering what is going on with my pony boy and no one seems to have any idea. Being a college student, I would rather not have to spend an arm and a leg on a vet bill for multiple things that it *could be*, so I figured if someone here were to have had a similar thing happen I could rule out some things.... or try to anyway :)
Bali keeps losing weight a noticeable amount, and then a week later he will look normal again, without any change to his diet/exercise/etc, and then lose it again, and then gain it back. He has done this two fall/winters in a row now, and to my knowledge it hasn't happened before these past two fall/winters. My family bred him so we have had him since birth. He's 13 now. Of course these two years have been our first time away from my mothers watchful eye on both of us so maybe I just never noticed it, but she doesn't recall this happening before either. We are also now in California, and he was born and raised in Colorado.
At the old barn I assumed it was because he was on pasture board and not getting enough food cause he was with a bunch of grouchy mares. But now he gets Breakfast, Lunch, Dinner, and supplements in a private stall and he is still doing it! He seems to know just when he's lost enough to have me worried enough to call a vet out because I'll go four days without seeing him (work sucks!!) and then he'll look good again. And not just to my eye, my barn manager and owner have said the same thing.
His teeth were done a year ago and he doesn't seem to have any problems eating. He was last wormed in October, they don't worm in the winter at the barn I am at... however I think I am going to have the vet worm him with the most wide spectrum wormer he can prescribe just to be safe maybe...? And the only other thing we are thinking is maybe it's his Thyroid.... would that have him gain and lose and gain again like this? I always thought if you have a thyroid problem it just makes you either lose a lot or gain a lot in one direction...? Would it happen more in the winter? He was fine all summer, fat and shiny and full of energy. It's not like our winters here are hard on him, he lived out in a field in the winter in CO in the snow.. here he's blanketed and in a covered stall with the worst thing being some rain or wind.
Sorry to write a novel, I am just concerned about my boy. Obviously I am calling a vet out either way for next week, but I was wondering if anyone had ever heard of this kind of thing or had an idea of what it could be?
