My yearling colt is being very slow to shed out his woolies. My other horses have all shed almost completely out at this point, but my colt has really only shed well across his shoulders and hips, and somewhat along his topline. I brush him and get after him with the shedding blade and rubber zoomgroom every day, and always get a huge pile of hair off, but there's still a lot more on. He's started getting sweaty when I lunge him, and he's rolling a lot and rubbing on the fence posts, terribly itchy.
He seems otherwise completely healthy, the patches where he has shed are coming in dark and slick like they should, he eats and drinks well, is a bright eyed, active youngster in every sense, he just looks terribly shabby right now. He's been wormed monthly up to this month, on my vets advice to worm monthly until 1 year (he just turned 1 year on April 1st) primarily with Ivermectin, but the last several months I have rotated with Fenbendazole. He's currently on no supplementation, just hay and pasture, and he went from being pastured during the day and stalled at night, to being 24/7 pasture with a run in a week ago, and the vet is coming out for a general check up and to see if he's ready to be gelded next month.
I'm probably going to go ahead and body clip him, but I was wondering if anyone has any experience with this and are there further health concerns I should be worrying about with a retained coat?
