If he's being difficult to ride and wont load are you sure it's the yard that's the problem - not something physical. I had a horse who was a shocking traveller if he was sore in his back, they have to work hard to balance while travelling.
Hi,
What a nightmare! Have you done anything since your previous post to try and help the situation ie change routine/field mates etc?
If you can and haven't already might be worth talking to yard owner - could he change stables/field. If he cant be left alone can you buddy up with another...
Have you spoken to your yard owner??
Why did you move from the old yard, if your happy to move him back so quickly you must have been happy there - just curious!!
