My absolute favorite that I have utilized for many years is the undercoat rake for dogs, it works sooo well! I mean the $3/$4 ones with metal teeth, not the fancy expensive ones. I end up with large piles of raked out hair, and begin using a brush when most of the winter hair is lost. Some of my horses begin shedding earlier than the others and quicker, and those ones always have super shiny natural coats and are closely related, maybe inherited very oily skin, who knows.
