The puppy has a pure poodle coat. He is currently growing out his puppy coat, so he's getting matts close to the skin. I have a slicker brush, a metal comb and some detangling spray, but it's a real battle. He hates having it done, and I hate doing it. I'm using my fingers close to his skin to try and stop the pulling, but I'm clearly not doing enough as he struggles like mad :( Any tips on how to get him used to this? It'll be an ongoing coat issue and I don't want him to hate me
