Tilly use to get terrible mats!!!! If you can't brush them out best thing to do is shave them. It saves them from having to go through so much pain. Try not to use scissors because mats can be close to the skin and it's hard to distinguish where the hair ends and skin begins, so they may get cut. Only brush one area no more than five times. I have found that a slicker brush and comb work great. There are a lot of great detanglers out there as well. I've heard Cowboy Magic is good. Haven't tried it yet though. I brush Tilly every other day now and she rarely gets mats. Since I have taken classes in pet grooming I understand how to maintain her fur better. I also keep her cut shorter. I hope this helps.
