Hello! I have a mare, Liz, who is thought to be in her mid to late 30's. About 6 weeks ago, she started mildly quidding her hay. She was making about 4 small balls per flake, so she was getting most of the hay and I wasn't too concerned. I got the dentist out about 3 weeks ago. He said that Liz's teeth weren't too worn down and that she only had a couple of small points that could have been bothering her if she was being dramatic. He took care of the points and Lizzie began quidding her hay less, although she was still making a ball or two once in a while. However, in the last week, she's started quidding her hay again, just as bad and maybe even worse than it was before the dentist came out.
Lizzie is on a complete senior feed and is getting a pretty good amount of her hay, so I'm not too concerned about her nutrition. Of course, I am worried about the possibility of her choking. The balls of hay aren't very big, but I like to be careful!
What might be a cause of the quidding if it's not her teeth? Any ideas?
