Would I purchase an hypp positive horse? No I wouldn't because I like to spoil my horses with any treat, not have to worry if this or that will stress my horse and trigger an attack, etc.
Do I own an hypp positive horse? Yes I do. And in a way, I'm proud that I do. I have found out a lot about the disease, I have told numerous people about it and am wanting to totally campaign (or something like that) to AQHA, ApHC, AtHA and all other registeries that can have Impressive in there to test against the disease.
When I first got Vega, I had NO idea what hypp was, let alone Impressive. It was only after I came on here that I learned what it was. I got her tested and was devistated when she came back NH. Before I got her results, I contacted her breeder, and asked if she ever had her tests. She didn't because she never showed a symptom and she thought she didn't have it. I had planned on stopping all training with her, but I didn't. I continued on but was more cautious for the first month or so. After that I kind of forgot about it. I dont mean that I'd feed her molasses and stuff, but I wasn't as paranoid that everything I do would trigger an attack.
Since I have owned her, we have changed barns, changed feeds, changed her exercise schedule and she hasn't shown one symptom *knocks on wood* But from what I read a horse can have no symptoms all their life, then have an attack. So I am always watching her, and if I see her twitch I immediately walk her (the twitch is from flies, since its in the summer, but I would rather be safe than sorry)
A few months ago, I put her up for sale and included in the ad that she was hypp N/H. I had quite a few people show interest in her. So I think people that only hear one side of the story will run, but people that do their research will realize that it's not that bad.
I know some of you wouldn't have one, and I wouldn't either, but sometimes things happen and you realize how much it opens your eyes to the world and to what's going on.
Sorry for rambling. think I'll stop now.
oh and BTW, Vega was on sweet feed and hay 2x a day and turnout in a dry paddock and had no problems. We switched her to a pelleted feed with either free choice hay or grass and turned out in a pasture. Again, no problems.
