Yeah, I had to deal with a lot of mats today! This guy is a trooper. Here is Shaggy, before and after:
How did I do it? #7f on the body where I could, #10 on the rear, belly, legs, and feet because I had to. #15 on the face because I had to! I neatened his pads and "dug out" the mats with a #5/8. #5f on the top of the head, skim on top but firm on the sides, then I scissor-neatened. Shortened and rounded the ears, shortened and "fanned" the tail a bit, and scissor-neatened feet and any stickeyouties, of course!
