So how are things going now eventerbabe?....with your horse, I mean.
He's got an argumentative nature anyway and i think my RI wasn't used to that (she's used to nice, well behaved obliging warmbloods!).
OP - I would have everything checked that could possibly be checked physically and get out a knowledgable NH person for an assesment before I made the decision to have this horse pts. I have had Mike Barker out to work with some of mine and have also been to some of his clinics, I do rate him very highly. Please feel free to PM me if you want his number, I still have it.
Please keep us posted.
