Hi,

I a matt breaker but I must admit I don't use it alot, I prefer to tease them out with my fingers, failing that a very good tool is a stitch breaker, its very good for breaking knots so they can be easily groomed out. One of my boys gets tiny little mats underneath as we have underfloor heating and he gets hot. The stitch breaker is very good and doesn't hurt them at all.

Im sure there are others on here that have used the matt breakers and who can advise you better.

Izzie
