LOL... And now you see why people scream... ick! Impressive, how awful! There is a thing called HYPP and you need to test your horse!
I have 2 impressive bred horses, My mare is out of Top Vantage who is out of Impressive. My gelding, is out of my mare. I LOVE the impressive line, they are smart, quick learners, pretty to look at and really can do it all.
The thing about the Impressive line is that when he came along, he was THE horse. I mean, if you wanted a quarter horse, that day and age, he was the ultimate horse (according to the quarter horse world) so everybody in there brother bred to that horse. It wasn't until years later that his offspring started showing signs of HYPP, back then, it didnt exist, so NOBODY would have tested for it. It wasn't until even many many years later (sometime in the 80's I think- which would mean that horse had been breeding and his offspring had been breeding for over 10 years at that point) that they were able to link the disease to Impressive, which means he was still being bred while they were researching the causes, effects, and origins of this desease. By then you had registered AND unregistered horses that carried those bloodlines. The next step would have been to SUGGEST people test for the disease, it used to be expensive, now I think it's only like $40. AQHA started a rule that they had to be tested at some point and now I'm not sure you can even register an HYPP horse. The disease isn't quite as common now, I'm not sure the Appy association or the Paint association has rules on testing or not, but they used Impressive lines as well.....
Sorry for the long story, just trying to make a point, although I'm not really sure what my point is? Other than, AQHA is trying to fix the problem, but you are looking at what? 30 years of breeding that line with tested and untested horses? It will take a long time to "fix" the problem and it will probably never fully go away....
I geuss my point is this... I love my Impressive horses... they are HYPP/NN............
