Bugs can make a horse lose quite abit of weight iv seen it happen. Bugs were iam are horrible if horses don't have a dark shelter to go in its bad. I mean that can't stand still for a second. Bugs are out full force by 9AM Flys that bite , horseflys, deerflys and mosquitoes.
Then night comes and the mosquitoes drive them to run to get away from the swarms. Sprays work for a short time but that's it.
If my horses didnt have their dark bug free barn to go into during the day theyd be skinny. Bugs drive them insane. Doesnt matter if they are on pasture 24/7 they still lose weight. So yeah bugs can take the weight right off and in a hurry.
Don't think that's the case with OPs horse but could be part of his problem.
