This is our mini "Tumbleweed." I had a bug up my butt today to shave him since he hasn't been shedding, his coat is extremely thick, and it's been getting warm out. Well, I started with the scissors to take some work off the clippers...then the clippers wouldn't work. Ugh, poor thing. IMAG0179.jpg
LOL, poor guy! I agree though, he probably doesn't mind one bit and feels a lot better. Just don't show him a mirror until you get your clippers working. I'm amazed that he stood for you to do that though. My mini mare is 5 but she'll barely stand for me to trim her feathers, beard, and bridle path! xD
But to answer your question, yes most of them do get that way. My girl gets SUPER hairy even though we live in Texas with very mild if non existent winters. Her filly, a mini mule, was even hairier. Sour (mare) is actually just now starting to look like a normal horse now, and shedding out nicely!
This is her typical 'mid spring' coat, with beard and fetlocks trimmed. Excuse how fat she was.... she's much thinner now.
