My goal is to start riding her again next week on a consistent basis. I am working my butt off trying to get our new house unpacked so we can have some semblance of normalcy there, and then I won't feel like I'm neglecting my new wifely duties by spending all my free time at the barn. So a change in feed plus exercise will hopefully equal a less pudgy pony. If the combination of those two things doesn't seem to help, we'll move on to plan B.
I've had quite a few people tell me my vet is overreacting and I agree with them to a point. Is she fat? YES. Is she obese and dangerously overweight? I don't think so... she doesn't have a cresty neck and she doesn't have any fatty deposits on her body. I certainly can't see ribs, but I can feel them with just a little bit of pressure. What has me a little worried is that two years ago, I was pouring the food to her and she was skinny. People kept telling me I needed to put weight on her, and I was working to add about 100 pounds of weight. Why was she such a hard keeper then, and she's such an air fern now? Have any of you had horses go from one side of the spectrum to the other like Lilly has? She has always had routine vet care and has her teeth floated once a year, so it wasn't an issue with chewing her food. It's just weird that she gets practically nothing to eat now and is so fat.
From what I read about IR horses, they go from being normal horses to fat kids that you just can't keep weight off. Lilly is twelve, and this is about the age where this kind of stuff starts happening. So while I'm taking a more cautious approach to the IR issue, I don't want to rule it out in case there really is something going on with her.
I will also be looking for healthier treats. I've been told that carrots are loaded with sugar (who knew?), so I need to cut back on those. She was horrified when I told her.
