Hello! I have an 8 month old, male tricolour rough collie puppy. He has a tendency to get matts right behind his ears, and it seems that every time I brush them out, they're back within 24 hours. It takes a long time to brush them out and he doesn't enjoy this. Does anyone have a specific product they'd recommend to help with this? Could anyone possible recommend a detangling spray or other product that makes grooming a little easier for us both?
