My mare was, I believe at around 3 years of age, trailed from Wisconsion to New Jersey. Don't know if it was all in one shot, but I'm going to say it was.
She was also trailered for like 15-20 min (not a long time I know) but she was fine.
I agree that HH horses should not be bred, but I also know that some people (people that show halter horses) would rather have a NH horse than one without because of the muscle definition. I'm not saying its right, just saying.
Before I knew Vega had hypp, I had thought about breeding her down the road. Though I have crossed that off the list just because I don't want anything to happen, or for the goal to be positive as well.
I would hope, down the road the registries would no longer allow NH horses to be registered, but that still cut out hypp since there are backyard breeders and all.
I just personally don't like how if someone asks about HYPP people say it is absolutely horrible because in reality, from a person that owns a positive horse its not nearly as horrible as most of you view it as.
I couldn't agree with you more!
