I was wondering the same thing. Finn's underside and armpit areas get so matted so quickly. He hates being brushed, will grown and snap and then roll around on the floor getting messy again. I need to cut the mats out tonight when he is sleeping little by little and keep trying to get him used to grooming. Part of that is that I left it be in the winter months because when the breeder dog sat for us she shaved him so he had no fur to brush until recently. Now when he goes outside he gets so muddy he needs frequent baths (which he also hates) and got all matted up on his underside. His upper side is fine. I am going to have to look into the products mentioned to start using with him as I work on clipping these mats out and getting his underside as untangled as his upper side |
