This is a quick how to line groom video, I apologize for the very poor sound quality!
What you want to do is brush with the straight comb straight down, using your hand to create a line in the fur.
For brushing her tail and hock hair, I use a slicker brush. First I spray her tail with conditioner, (DO NOT use a slick on any part of their body except the tail and hock hair, and use conditioner (diluted is fine, that’s what I use) first.) Then I brush in the opposite direction of her fur.
I keep up with Bambina’s coat, and if you keep up with your dogs coat it’ll be way easier. I’m sorry, I didn’t have time to show you have to line groom their “mane” I’ll do that at a later date 🙂
