Regular grooming is the best way to prevent mats. The environment, however, may also play a factor. In dry seasons, particularly winter in colder climates, mats are more likely. Use a humidifier or diffuser to add moisture to the air to help maintain your pet’s coat. While you shouldn’t try to use a dematting comb on wet fur, it’s recommended that you mist your dog’s coat lightly if you’re brushing and grooming when the air is dry. Regular bathing can also help prevent mats. The frequency will depend on your dog, but once every month or two is common. Also, a simple way to prevent matting around the neck is to remove your dog’s collar when it’s indoors.
