I have a horse that was Dx with EPM. I have him currently on the Marquis. I would like to know should I excercise him while he's on this ? I'm worried about any muscle atrophy. Should I be streching and/or massaging his back quarters or maybe just walking him would help. He's in a paddock approximately 120ft sqr. with a younger horse to keep him moving. I didn't want him to stand around alot. Is there anything special I should be doing besides praying? I would appreciate any info anyone can offer. Thank you Marie B
