I found a great match for me...he's about 20 years old. He is safe and steady and patient, a great boy! However, he has suffered a bit from his previous owner (s) and is sensitive on his back when tacking up and he is very grumpy being tacked. I know you have all heard this story a million times but what can I do to reassure him that I won't hurt him and also what can I do to make sure I don't hurt his back the way it had been in the past? I have a great fitting saddle and use a thick pad on top of a baby pad or regular square (close contact) pad. I want him to be better not worse than before I got him. Can you tell me which pad you may have used to help fix back pain in your horses and please share your experiences with this. At first I thought he was cinchy so I have been using the fleece girths instead of leather ones but what else can I do and which pad works best to fix back troubles? I ride english (hunters). He is such a sweetie I want him to be happy.
