After Harley successfully bit me in the arm last night (he just pinched the skin, but it was enough), I decided to consult my vet about ulcers. If he had done this to my daughter... well, that might have been it for their relationship. There are a lot of things I can take from a horse, but not biting. I went after him hard, but I feel bad if he's in pain. And he was very, very girthy so it seems to be getting progressively worse. I've been looking at ulcer treatments, but there are a lot out there and not all are available locally... furthermore, I'm the kind of person who likes to get to the bottom of things. So I called my vet who told me to bring in a fecal sample. While they're at it, I will have them test for worms too.
Now I understand that signs of ulcers may not show up in a fecal sample. He also told me that scoping might not reveal ulcers in the stomach, but there could still be some in the intestines so that isn't foolproof either. If they find signs of ulcers, we will start an aggressive treatment. If not, we will start a milder treatment (consistent with low-level ulcers). So either way, he will be getting treated.
I'm going out of town this weekend and will see if I can find a wormer that contains Moxidectin. There are none locally.
Just wanted you all to know that I am following up on this. I hope to get results shortly and will let you know what comes out of it! Have to go stand in his stall now and wait for him to poop (they asked that it be as fresh as possible)... fun!
