Mando is 10 months old and I'm pretty sure he's blowing coat. I comb and brush him every day but he's still getting mats behind his legs, armpits and sometimes ears. What's the best tool to deal with these? I've got the CC combs (face/feet and greyhound) and wood pin brush. Sometimes it takes almost an hour to get rid of a mat and it's not fun for anyone involved. He's in a longish puppy cut. Am I missing a tool that would make life easier (e.g., slicker brush, de-matting rake, etc.)? Any suggestions from the pros on here?
