I have a three year Connemara Sporthorse gelding. I bred him for myself out of my OTTB mare - foaled him out and have done all of his training to date. This is my first baby, but otherwise consider myself an experienced horse person, having ridden for 30+ years including restarting multiple OTTBs myself.
Anyways, I brought my gelding to a well respected cowboy type trainer to be started under saddle. He did okay the first week, even participating in a versatility/desensitizing clinic with me as the handler. Since then, his behavior has completely deteriorated. He has become extremely explosive, over reactive and sensitive to work around. We thought maybe ulcers, as he also had anorexia and weight loss, and have been treating with Ulcerguard for three weeks. His weight has improved, but he continues to be reactive and difficult to work with, to the point that the trainer told me he couldn’t ride this horse.
I had the vet out to rule out physical causes. We did pull a Lyme and he came back mildly positive for a chronic infection (Osf 2862). He has an appointment to get scoped for ulcers next week. He also had a lameness exam as he was briefly “off” last week, though that has since resolved.
Here is my concern. He has always been challenging. Even as a foal, he hated to be touched and had no use for humans. We got through that, then he started bolting when being led. I had another trainer out to help me with that and we made some real progress. I have not consistently worked with him because of other commitments, so I jokingly say he is semi-feral. But he got to the point where I had tack on him and was hand walking him up and down the road and all around our farm. He is now fairly sweet and sometimes even cuddly, but is always looking for that cheeky opportunity to misbehave.
But now it has just completely deteriorated to the point where I was appalled and embarrassed by how terrible he was for the vet, like borderline dangerous! And this is with five days a week of training with a well-regarded trainer with extensive experience with problem horses and babies.
I’m going to bring him home this week and with my vet, will continue to try and rule out physical causes. I am so disheartened that this young horse who I have waited so long for has turned out this way. Is there anything else I should be looking at or considering? For all you experienced breeders out there, have you ever had a young horse that is just too difficult to even be backed?
