Hey all, the vet was out last week. He says my mare is 150# overweight. She gained 80 more since the last time he told me she was too heavy. My question is, what kind of exercise regimen can I start to help her lose weight and condition her. Currently she is on Enrich Plus 1/4# twice/day and she gets about 15# of grass hay/day. She was given 4# of alfalfa/day all winter, but she rarely gets that anymore. She is kept in a paddock with very light grass. We do have a round pen. Thank you in advance for any input!
