We had an Impressive horse that died from it. That being said I think our Fancy (Fancy Me Quest out of Impressive Quest) Was a fabulous, beautiful horse. Its the disease and the way the AQHA handled it. The disease could have been bred out in 2 generations if they had acted on it. Instead they went with the big money breeders and did nothing. I think Impressive horses are one of the best for halter class too. If they had just bred out the disease sooner we wouldn't be having this conversation.
Because they acted the way they did we will never own another Quarter horse.
I lay it all at the feet of the AQHA
