Hello everyone I have a question that I am battling around three weeks now. I consulted with my vet we did all tests possible and now everything is supposed to be okay. So to tell you the situation:

I bought 2,5 years old mare of Aph at the end of August. First week that she was with us she was acting like depressed or sad with her face expressions but I thought it is because of the new environment. But then she started to worry me. We started with slow gentle training for walking and respecting personal space because she was not aware of my personal space and was being dangerous around me. So the training was just basic horsemanship nothing more. But she started yawning excessively and looking apathetic. First I noticed it after training but then I noticed it on pasture as well. She is acting like sleepy person whenever she is asked to do something or go somewhere. The we did all of the vet tests to make sure she is okay which came back good. She has everything she needs. So I tried not taking her to working area and yawning stopped. Now I took her there again but just to have fun and fool around she got treats but the second day she stared yawning again when she is in a working area and even when she is just standing there not doing anything.

Can you please help me interpret this behavior because I am truly sad thinking that maybe she is not comfortable or sad and it is painful for me to think that something is not okay but I cannot determine what it is. I will be glad for all of your advices. Thank you so much ❤️
