She has a bit of a belly. She's USUALLY ridden 4x week (occasionally give or take a day) and we are gradually increasing fitness. BO said that we should muzzle her to get off the belly. Not sure if I should cut back on grain, muzzle her, etc. She's never been muzzled before (she's kept "naked" outside usually, sometimes blanketed in the winter but never even haltered).
I don't need her to lose a TON of weight but we need to cut back on that little belly. What would you recommend doing? Thanks :)
