Hey all. We are trying to sort out what to do for one particular horse at the barn. She is an off the track thoroughbred mare that has forever and always been “sharky”. She tries to bite you (not pretend, like if she gets you, she gets you!) when brushing, she will threaten to kick you when saddling her and adjusting the girth from the ground. You even have to be a bit careful walking her to and from the barn for turnout, etc. When you are on her back she can be nappy to start, doesn’t want to go forward or take contact, but after about 10-15 minutes of warming up, she becomes a beautiful, in your hand, hunter. Jumps a 10 and never stops - seems excited to do her job at the jumps. Now here is the kicker - when she is in season, she is the sweetest mare you have ever met! In your pocket, snuggles, kisses, loves to love, etc. Absolutely NO issues! We have talked to two vets - they say she’s just crabby. Owner had a saddle fitter out and just bought her a new saddle. She likes her new saddle but is still crabby on the ground. Tried to get her massage therapy this weekend - she had some huge releases, but then in a split moment, kicked the therapist and decided she had enough. Have done chiro and there was nothing remarkable noted. She’s on a few supplements - MSM, chasteberry, biotic 8. We have tried recommended ground work exercises, brush and lunge, etc., etc., but nothing seems to make an everlasting impression on her. Time off makes her more crabby, it seems like she enjoys having a job. She has friends outside, she loves her full day turnout, is happy in her stall at night too.
Can anyone shed some additional light? Is she just sharky? Can we fix this through X,Y,Z? Have you had a horse similar? Thanks
