Hi there and thanks for using Petco Pet Education Center, formerly Petcoach!

My first worry with older horses is their dentition (teeth). If you have never had your horse's teeth floated, it may be time for that. Lost teeth, impactions of feed, uneven wear, etc can all affect how much and how comfortably your mare eats. Your vet can perform this, after an initial exam.

Best pulp can be good to put some weight on them, if it's a simple caloric factor.

Last but not least, if you haven't dewormed in a while-consider taking in a fecal sample to your veterinarian to be checked.

These simple things I try to take care of first, I hope this helps you!
