I tried all sorts of different combs/brushes on Livi. Her groomer finally told me that I need is a regular comb.

We bought a cheap dog groomig kit from Wal-Mart....comes with a razor, scissors, blade guards and a black comb. That's the comb that I use and believe it or not, she looks the best when I use this plain ole comb instead of the dog ones that we own. Go figure....
