Grooming a long-haired pet requires regular brushing to prevent matting and tangling of the fur. It is recommended to use a slicker brush or a comb specifically designed for long-haired pets. Start by brushing the fur in the direction of hair growth, focusing on one section at a time. Pay close attention to areas prone to tangles such as behind the ears, under the legs, and around the tail. Additionally, regular baths with a pet-friendly shampoo and conditioner can help keep the fur clean and manageable. Lastly, trimming the fur around the eyes, ears, and paw pads can also help maintain your pet's grooming needs.
