Nilla lately has been getting these terrible mats that I cannot get rid of. I've been trying to break them up with scissors and brush them out with my Madan, but she doesn't want to sit still for it and it is infuriating! I read somewhere it may be a good idea to get a mat rake for such a problem, but what are your opinions on this? Has anyone experienced this problem? I recently switched her to a Happy Tails shampoo and I was previously using Earthbath Puppy shampoo. I'm beginning to wonder if that isn't the problem ... If anyone has opinions or suggestions, please feel free to reply! Thanks!
