…My aunt lives where we are keeping him and my other gelding, so she was coming outside and feeding him apples, carrots, and other treats. We didn’t know she was feeding him, so we were giving him apples too. After the first day of sickness, he stopped getting apples. Yesterday morning, he had a quarter of an apple cut up, and that afternoon, he had the symptoms again. …[/QUOTE]
I would bet that it’s the apples. I have one who did the exact same thing when he ate apples - even just a quarter of an apple. Minor colic symptoms but nothing major - just not right.
Needless to say he hasn’t had a bite of apple for years now - and has never had so much as even a little upset stomach. In my horse’s case it was definitely, without a doubt, the apples.
I would suspect your horse is the same. Easy way to test the theory - just don’t ever give him even one bite of an apple. Hopefully that’s all it is and your problem will be solved.
However, I’m sure you know that if the symptoms return anyway, you should have your vet.
