I have an Impressive Mare (Impression In Time, out of Impress Me Shanon)
I got her tested and she came back NH. She has not had any symptoms and is on a low potassium diet, and is doing great.
The thing that stinks about it is, that I can't go out and just get any kind of horse treat.. I always have to look at the ingredients and the potassium levels and if the box doesn't have anything, I don't get it.
Can I live with it? Yes. Does it stink not being able to get my horse anything I want? Yes.
I think Impressive horses are gorgeous, but I wouldn't get another one again, atleast not another that is hypp positive.
