This week, we had an awful workout - his trainer and two other seasoned handlers worked him for 1.45 hours and at the end of the session, he kicked back twice. The second workout the next day he didn't kick out at all.
So here is my quandary. The trainer says to sell him because he is dangerous and unpredictable, or put him down. The mother of the previous owner said that the owner used to ride him all the time (saddle was a bad fit) or they put pallets behind him and he pulled them and it was fun. She stated that this behavior is unusual and usually he is sweet and gentle.
Could this behavior be because he has had so many changes in his life in such a short period of time and we are working him and he is not used to it? The previous owner had so many health issues that she couldn't work him properly at all during his 4 years with her so he is so green.
Do I give up on him and sell him or hope that with proper training he will come around? He isn't dumb and is very smart.
Any advice would be great!
