I have a 4 year old welsh pony that has never had any problem with weight...she has always been 'pleasantly plump' but I've been noticing lately that her hind end does not match the rest of her. Her belly, shoulders, and neck are nice and chunky and filled out. She gets ridden 4-5 times a week, with all sorts of variations in and out the ring with every ride.
I guess I am trying to figure out if I can try a muscle builder or just live with it, that it is the way she is built??
