Long-haired dog breeds typically require regular grooming to prevent matting and tangles in their fur. They may need daily brushing to keep their coat in good condition. Regular baths using dog-specific shampoo are also recommended to keep their fur clean and healthy. Trimming or clipping their fur, especially around the eyes, ears, and paws, may be necessary to maintain their appearance and prevent discomfort. Additionally, long-haired breeds may need professional grooming services periodically to keep their coat well-maintained.
