There is no specific guideline on how often to bathe your dog, although certain factors like quality and texture of his/her coat will be a good indication. Look for matting, build up, oils, and smell of the coat to determine when to bathe your dog. Regular brushing can help extend time between baths, and keep the coat clean, especially during times of shedding. Keep in mind that bathing your dog too often can rob his/her coat of essential oils and conditioners, and lead to irritated skin, and a dry, damaged coat. Always use shampoo that is made especially for dogs for proper pH balance and conditioning.
