When matts are small enough, they sometimes can be combed out. However, if the matts are bigger and close to the skin, they cannot be combed out as it is very painful and not safe for the pet. De-matting (the process of removing matts by combing) can be extremely painful and traumatizing for the pet. We recommend starting out fresh. In case of severe matting, our groomers will shave the poorly managed matted coat and start out fresh. After shaving, keep a close eye out for itching and hot spots. Severe matting sometimes requires the attention of a veterinarian as it can cause problems such as hematoma and hot spots. All precautions will be taken. However, problems occasionally arise, during or after the grooming, such as nicks, discomfort, and clipper irritation.
