I have bought the slick n easy blocks, but I don't care much for them. It's easier to just use a shedding blade, IMO. As for the vacuum...can you believe I do not even own one? My last two died on me so I ripped up all my carpet and just gave up, lol. I think my mom has a small shop vac though with a couple of brush attachments...maybe I can borrow that.
My friend brought her wooly mammoth to the arena yesterday and was using the furminator on him- the amount of hair that horse shed off was astounding! It looked like someone had put a rug on the ground when she was finished, lol. And he was still not completely shed off, but this horse is HUGE and he has enough hair to keep three horses warm even in the summer. I suggested to her that she might consider giving him a body clip this summer because his hair is so thick. I am not normally one to suggest body clipping, but in his case I think he'd be more comfortable when it gets up to 120 degrees, lol. I am fortunate that all of mine usually shed off fairly quickly with minimal effort and have pretty slick summer coats.
