My 6yo pony mare has been out in training for 2 years. She has always been very sensitive and had various irritability problems which we treated with Regumate, healed an ulcer, used anti anxiety med, all with some change in behavior, but never a happy pony. When being ridden she would pin her ears and wring her tail. Three months ago she started refusing jumps and I brought her home, gave her full time turnout in good weather with pasture mates she gets along with, took her off regumate and did not have her ridden for 3 weeks. She was then ridden once a week with no jumping and seemed to be happy to be back at work, but still with the flat ears and tail going on and off.After 2 months of this regimen she suddenly became very upset under saddle, prancing, going backward. When I put her on a lunge line she arched her neck, flattened her ears, DrOpped her shoulder and came at me! In spite of all the irritability in the past she has NEVER shown any aggression to a person before.

My vet put her back on Regumate and gave her a shot of Depo, and after 2 weeks she is a little bit better, but still would like to run me over. On a lead line she is sweet and willing. I had a trainer look at her and she never saw anything quite like it.

Does anyone out there have any experience with this kind of problem or have any suggestions? I am at my wits end with this pony and just want her to be happy!

Have you checked her for a granulosa cell tumor Kathleen? Besides infertility the hormonal problems can make for a very aggressive mare. For more see, Equine Diseases » Reproductive Diseases » Trouble Settling Mares & Stallion Infertility » Granulosa Cell Tumors in Mares.

My vet thinks this is not a health problem since she is fine when out in pasture or being led. Only when you ask her for something does she show aggression. He thinks it is more a behavioral problem, with her brain being fried from her past.

Do you agree with this?

I think it would be short sighted not to see if this is the problem even if a long shot as it is fixable if present.
