If you own a Coton de Tulear you will ultimately at one time or another get a mat. The Les Pooches emergency MattZapper brush has been highly recommended time and time again. I have been told by breeders who show their Coton de Tulear's that they are careful using it and very satisfied with their results. For companion owners it can be the difference between saving your dogs longer coat and having to cut your dog back. We all have challenging moments grooming our Cotons but with patience, practice and the right tools they do become less stressful.
