True, dogs don’t need to be bathed at all. But I wouldn’t doubt that some dogs are smellier than others. Bloodhounds, for example, are known for smelling bad. They seriously have their own musty body odor!! Usually dogs with wrinkles, folds, and drool, get smelly quicker. There’s nothing wrong with bathing your dog as long as you’re not doing it every week. I’ve known Bulldog owners to use baby wipes on their pup’s wrinkles to prevent bad smells and infections.
But for your normal looking dogs, only clean them when they’re messy. Bathing too often dries out the skin and damages the coat.
