Under normal circumstances, Teddy's hair should be cut once every three months. Longer hair can play a certain role in keeping out the cold. In summer, it can be cut every other month or so to help the dog dissipate heat. When trimming your Teddy dog, try not to shave the hair. Especially in summer, not only will it not help the dog dissipate heat, but it can also easily cause skin diseases. It is best to leave about one centimeter in length, or you can take the dog directly to the pet store. Have it trimmed by a professional.
