Over the past 5-6 weeks we have noticed our horse seems to be deteriorating. With the weather change we thought his winter coat would start to sluff and he would be shiny again. Not so, it's coming off but very shaggy and rough...not like our other horses. We figure he has probably lost 100 lbs. his muscle mass has diminished and he has started eating his own manure. We have a salt lick available always. We feed Bermuda grass 3-4x/day and sometimes supplement with alfalfa or orchard grass. We wormed with zimectrin. We found some fly issue in his ears, not sure what it was, and treated it with a solution of 20cc's frontline and mineral oil. I think we need to supplement with grain or beets or something with move vitamins and calories. Need some good advice from all you horse experts out there.
