I have an 8 year old stationbred pinto that is nice to ride and generally respectfull.The problem is he is sacred of his covers, and also very wary of saddles,blankets and farriers with flapping aprons etc. I have done quite a lot of approach retreat desentisng with him and he seems to relax and I think the problem is solved but the next day we are back to square one with him. He tenses up and holds his breath whenever he feels wary and pulls back madly if he is tied, but ok tied if you are not doing anything with him. I am not sure if he has had a big fright , wether he has been abused at some stage or wether he just hasn,t been broken in very nicely. Any advise would be appreciated. I have owned him for 6 months and don't feel we have really made any progress with these problems.please help!
