So true, do not use the plastic tipped pin brushes. It ruin the coat..
Have you tried products from Vellus?? Specially for yorks...
I really love the shampoo and conditioner..
Give your dog a bath, and then use the Vellus Satin Creme. Mixed in a little bottle with some satin creme and water.
Spray in your hands and groom with hands trough the coat.
Then blow dry (not warm) and brush at the same time!!!
You can also add some more after your dog is brushed and blow dried...
I think the only thing that helps from breaking is to oil the coat and role it in paper....
