If the hair is allowed to knot or develop "matts", this is unhealthy for the dog's skin. Knotting gets worse if the coat gets wet. Before washing the dog, it is necessary to brush out all the knots. If the hair is matted, it may be possible to "dematt" the coat. Unfortunately, this can be painful. In some cases, dematting may cause or reveal skin irritation. If your dog is matted, we will advise you what can be done. If the hair can be dematted without causing pain to the dog, it may be possible to save the coat. Otherwise, we may recommend cutting the hair short, which means applying the clipper behind the matts. If the hair is matted, we recommend meeting with one of our groomers beforehand so we can discuss your options.
