He hasn't been bathed yet this year, we had a cold spell. He gets 2cups of brewers yeast and 2cups of alfalfa pellets once daily, 3lbs of unsweetened grained 2x daily, and about two flakes of grass hay at night. He gets 1/4cup of "healthy coat" supplement at night. He doesn't really have dandruff. He has a mineral salt block in his stall, and a white salt block on turnout. He's turned out to pasture from 7am - 5pm. He's on 60acers of grass so there is no shortage of that, they also offer a round bale of grass hay too.
The vet was out a few weeks ago because he had an Allergic reaction to some sort of wood in the sawdust and it was making the hair on his body fall out, the skin was dry and scabby and was kind of ***** where he'd been itching it raw. He said it was not to worry and and gave him a type of steroid injection and told me to give him some every other day, which I did and the problem cleared up. Now, I'm having a problem with his mane. His tail is fine, I brush it with a human comb weekly, and a stiff brush/bristled brush daily and there are never more than normal amounts of hair being pulled, usually between 5 and 10 strands. His mane I brush daily and that seems to be falling out quite a lot. He's not rubbing it, I've checked his stall, and there are no broken hairs. I considered putting MTG or some sort of Moisturizer just in case but i didn't want to destroy anything that the vet might need to see.
