Looking for some ideas please.
My sweet lovely mare who has never showed any aggression in the the two years i've owned her has started to try to bite and kick out if i brush her or touch her sides. She reacts when her saddle goes on her back but her biggest reaction is when i brush across her ribs. When ridden she is moving better than she ever has, really working well. Her previously stiff and difficult left reign is now lovely. After being ridden she seems more relaxed and less reactive when i brush, stroke her.
History: Kick in the rib 2 years ago, vet found bruising but nothing serious. 4 weeks off work to allow the bruising to fully heal and she was fine.
I've had an epic battle to find a saddle that fits well due to her changing shape from an hunter to a dressage horse. Found a perfect semi flex earlier this year that she moves beautifully in. I've booked the saddler to come and check the fit remains good.
Physio has seen her twice in 8 weeks. Last visit was Thursday. She found her to be reactive across the ribs but after a good poke and prod she relaxed. Mare was better Friday but today back to trying to bite again.
I've spoken to vet who suggested saddle check and physio before further investigations. He said he'd expect there to be more signs under saddle if it were ulcers or overies. She comes into season regularly and is very interested in the boys. In previous years she has never shown any sign of aggression even when fully in season. Just the opposite, usually she'll lean on me to get a good scratch.
I would never ride a horse if i believed in doing so i'm causing pain, currently she actually seems to benefit from moving. I'm lunging before getting on her even to hack just to be sure she's sound, comfortable etc. I'm just not sure i should be riding her at all.
I'm continuing to investigate but i'd be interested in peoples thoughts/ideas.
