I have a 5 year old QH gelding that is VERY VERY aggressive to other horses!
My mother purchased him as a weanling, she had 6 foals off of him before he was gelded. After gelding him (at age 4) the problems started... Can horses react to anesthesia the same way humans can sometimes?
While he was intact, he was very well behaved. He was always turned out 24/7 with my TB gelding, who is very alpha, but not aggressive. Two weanling geldings, and a boarders arab gelding.
QH stud, was not buddy sour/herd bound and was easily taken away from his buddies to be worked. He was also quiet around the mares while being handled.
After he was gelded, he was turned out in a small turnout area with a shelter for 5 weeks to heal. His friends were all on the other side of the fence to him. After his healing time was up, he one day turned on my TB gelding and they fought brutally. Biting, kicking, chasing. After removing TB gelding, he then turned on my two, two year old, submissive geldings. He chased, kicked and bit them until they bailed through my fencing to get away.
Since these incidents, he has also run through electric fencing to chase other geldings. He's even jumped into pastures, to fight other horses.
Recently, one of my mares was in season and kept ducking under the electric fencing and coming to visit him. After insistent escaping, we turned her out with him. All was well for a few weeks. Then he turned on her too, and they fought until they went thru my fencing.
QH gelding is now turned out in an arena by himself, and he's not happy... He has hurt enough horses welting them with kick marks, covering them with bites and forcing horses to run fences to escape. I Love QH gelding to bits... But Im sick of this.
However, he is still easy to handle. Leads, ties, luges etc. He is also quiet in his stall, even when leading other horses past him.
Whats going on in his head and is there ANY help for his behavior?
