While the Shar-Pei is a naturally clean dog with very little odor so frequent bathing isn't necessary for the Shar-Pei, but when you bathe him, dry him thoroughly. The wrinkles and skin folds are an ideal breeding ground for fungal infections. Brush your Shar-Pei's teeth at least two or three times a week to remove tartar buildup and the bacteria that lurk inside it. Daily brushing is even better if you want to prevent gum disease and bad breath. For his nails, trim once or twice a month. For his ears, carefully check weekly for redness or bad odor. Remember that their canals are small and are prone to irritation and infection. Do not use a swab to clean the ears and take care not to get water in them when bathing. Don't insert anything into the ear canal but just clean the outer ear.
