The one thing I am most worried about with her is that when I ride her, and only when she is worked, she tends to breath heavy for a short period of time. It only takes about two minutes for it to go back to normal at a nice brisk walk. She is overweight and on a scale of 1-10 I would rank her as a 7 or an 8. Also we are at 6,500 ft. Elevation, but before that about 1,000 ft. Elevation. We have only been living here in New Mexico for about three months.
But she still had the breathing problem when we were in Texas it just took a lot more working before she began to breathe heavy, and took her about the same amount of time to calm down. I would like to know what kind of check should I do for this. And also what kind of checks should I do prior to breeding (Artificial Insemination) to make sure that she is fertile and able to carry.
Here are some pictures of my mare.
