Has anyone tried the "Magic Coat Pro de-Matting tool" as a preventative measure on their cavs? It claims to take out the dead under coat, preventing mats and also helping to get rid of them when they occur. Pippa has very fine hair, so even with daily brushing she gets matted in her armpits. Further more if I use her harness she gets matted where it goes on her belly (very frustrating).

She's also been getting pretty warm with the hotter weather, and though I don't really want to get her clipped (unless I have to) I'm assuming having some of her undercoat gone will make her a little cooler.

The comb:
