Looking for non veterinary suggestions to try for a horse that can be a little cold backed and grumpy about going forward. Horse has been thoroughly vet checked from head to toe with a fine tooth comb. Super, super sound with CLEAN x-rays. Does not palpitate sore on neck/back. Treated for ulcers just in case. Currently trying Regumate but it’s a little soon to tell whether that’s having an impact. Will try Mare Magic type supplement and Purina Outlast in the future if the Regumate doesn’t seem to make a difference.
Behavior is that when you put the saddle pad down on her back, she pins her ears. Big pin and ear swish when you put the saddle on. Has a custom fitted English saddle ordered just for her but displays the same behavior no matter what saddle you try. Even more when the girth is done up. Walks under saddle with no grumpiness. Pitches a fit when asked to trot. Then, after a lap or two (or even better if you do a lap ot two of canter) settles in and is perfect-- forward and happy to work. Doesn’t matter who is riding, what saddle you’re in, whether she’s had days off or not, company in the ring or not, etc. Lunging first doesn’t make a difference. Still really grumpy the first time she has to trot off with a rider.
Looking for ideas for things like back pads, different types of girths (have tried a standard leather type and the cheap fleece and fabric type), supplements, routines, etc. that have worked for you for a horse with similar behavior.
