His "summer coat" you can bury up to your 1st knuckle in fluff, it's LONG, like a short hair cat length. His winter coat... You use a comb on it not a brush... Some of it gets 4 or more inches long... and then his beard.... it's ridiculous... he'll still be alive if he gets dumped into an ice age... but, his little legs are too short to handle any significant snow, he can't move in 2 foot of snow so he stays inside (with the hay and water tubs) while the others wander around outside...
On a mini forum, they regularly post "before" and "after" pictures of the spring clipping sessions. It's amazing to see the equine equivalent of an Old English Sheepdog get transformed into a dainty halter champion by a pair of clippers. Mine don't get quite that wooly, but they look like there's a whole lot less to them come summer. Which reminds me, I need to get some pictures before they start fluffing out again . . . in the next week or two.
