Kim, from your horses record, he has had lots of
experience, and you two have been together some years. I'd be curious if you
have seen a change in him at the last few rides. On the metabolic issues, were
they the same at each ride?Also, how old is the horse? Maybe there is
something going on inside him besides the conditioning. Have you had a blood
work up??? Might be a good place to start. Good luck with him.
