Hoping for some insight. My 7yr old Belgianx mare has this past fall/winter started having muscle tremors/trembling plus heavy sweating while riding her in anxiety producing situations. She doesn't have trouble moving and her muscles aren't tight (like in tying-up). If she gets amped up/ nervous this happens. Any thoughts? It's not every ride, but it's happening more often than not. Only happened once about 2 years ago when she got stressed on a camping trip but quickly subsided. I'm stumped.
Thanks for any ideas.
