should I be concerned? Stomping, tail swishing, sudden behavior change
I have been grooming and lunging my mare without any real problems. The first couple times she would attempt to change direction herself, but was easily corrected and has not been a problem since. Friday she was lunging beautifully! Well today the mare seemed off. When I was brushing her she was stomping her hind legs and swishing her tail as if there were flies (there are not, and no other horse was doing this). She wasn't trying to get away from me, no ears back or anything aggressive. It didn't seem to improve by stopping the grooming either. I thought perhaps she was impatient and ready to go, but when we started lunging she was like a different horse! She was cutting in on the circle, which she has not done before. Trying to change directions, and much harder to correct. She even broke into a canter on her own, which again was very new behavior. Although I cut the session short, I did work her both directions at a walk before stopping; just in case this is just behavioral I didn't want to end our session with her cantering around like a nutcase. She is not generally a challenging horse, this was very out of the norm. I understand horses can be testy, but I just don't want to overlook a potential problem. I did afterwards I did notice her standing with her front legs crossed; I've never seen that, not sure if maybe its just something horses do?
I'm naturally concerned, but can't really put my finger on what's going on. I'm debating if it's worth calling the BO about to keep am eye on her. I thought colic, but she doesn't have any other symptoms. Also she doesn't appear lame. Please help! Thanks!
And I apologize if I am way over reacting, I just worry
