The barn owner where I take lessons purchased 3 horses (2 geldings and a mare )from the same person in March of last year. King, the gelding that I was supposed to work with was really good in the beginning, however he didn't like to be seperated from the mare and became very uncooperative. We tried putting the mare in a seperate pasture with another group of horses and the mare jumped the fence and went back with King. I finally made the decision to give King to a friend in July that lives at a different location. Since King has been at her barn he has matured and gets along with the other horses but my friend wantsme to take him back due to financial reasons. I want to take him back but am worried that he will go back to the way he was before, however the mare is currently in a different pasture. Any suggestions would be greatly appreciated.
