This helps to loosen dead hair and to stimulate the skin. It is important to have the proper brush. Short bristles are for short and medium haired dogs and long bristles are for long haired dogs. Use a flannel cloth to bring out the shine in your dog's coat after brushing. If you dog is a long haired dog, some matting of the hair may occur.
Matted hair can occur from burs, food, tar and other sticky substances.
Matted hair is not only unsightly but can also irritate the dog. Try combing gently to remove the mat. If it is too tight or large, you may just need to cut it off. The fur will grow back in time. Always use blunt end scissors to cut.
