Long-haired breeds refer to animals, particularly cats and dogs, that have longer fur compared to short-haired varieties. These breeds often require regular grooming to prevent matting and tangles in their coats. Common long-haired dog breeds include the Yorkshire Terrier and Shih Tzu, while popular long-haired cat breeds include the Persian and Maine Coon. The long fur of these breeds can provide insulation and protection from the elements. However, it can also lead to increased shedding and allergies for some people. Owners of long-haired breeds should be prepared for the extra maintenance involved in keeping their pets' coats healthy and clean.
