Too bad about Molly. I don't have any experience with horses so I can't offer any suggestions, just my support.

The others have certainly offered some great things to try. I'd say it's worth a shot.

Horses have a special place in my heart. When I was a child, I begged my Dad for a horse, but we lived in the city. I have friends with horses and a couple of times a year I spend a weekend making horse treats; cookies and muffins.

Hugs to you and Molly.
