The old conception that you only need to give bath to your dog once in a month is completely wrong and is not based upon any medical fact. Veterinary dermatologists are suggesting that you should bath your dog at least once a week or whenever he gets dirty or smelly. More frequent bathing may help keep your dog healthy. For example, dogs with skin diseases should be bathed more often, even daily if necessary. Not only does it keep their coats clean and manageable, it also enables you to do a quick health check to ensure your pet dog stays in tip-top condition. Dogs with allergies typically itch less when bathed frequently with a branded product bought from a reliable dog grooming shop.
