I've had this problem with my samoyeds in the past and Ilya this season.,... his behind is getting very poofy and thick. He doesn't like the comb or the rake, however, I was determined to get the dryer, dead (?) fur off his behind. After 15 minutes, and a pile of fur, it seems like I'm not getting much off and it still has the "over fluffy" look. I wanted to wait just a little bit longer before he is obviously blowing his coat before I use the furminator.
