The answer for “how often should I wash my dog” will depend on the type/breed of dog you have, age and activity level.
Bathing your dog isn’t just good for their hygiene, it’s also an excellent chance to check for unusual scratches, bumps, fleas and other abnormalities. These things are easier to see when their hair is wet and flat against their body. But how often should you wash your dog?
Breed/ Coat Type
Margaret H. Bonham in Dog Grooming for Dummies says:
“Hairless dogs require weekly bathing followed by moisturizers and sun-screen. Remember, they’re as unprotected from the elements as you are, so put them in T-shirts or sweaters to keep them warm after a bath at night” These include; American Hairless Terrier. Peruvian Inca Orchid. Xoloitzcuintli (Mexican Hairless Dog) Chinese Crested. Argentine Pila
“Short-coated dogs usually need more baths than medium-coated dogs. Bathe your short-coated dog when his coat gets dirty or feels oily” These include; Boxer, French bulldog, Pug, Doberman, Dalmatian, Grey Hound, Great Dane, Weimaraner, Mastiff, Boston Terrier, Daschund, Beagle.
“Medium-coated dogs need to be bathed when dirty, but they also need to be brushed more, depending on the dog’s skin type and how often the coat gets oily.” These include Akita, the Australian Shepherd Dog, the Border Collie, the Brittany, the Cavalier King Charles Spaniel, the German Shepherd, the Golden Retriever, the Pembroke Welsh Corgi, the Pyrenean Mountain Dog.
“Bathing double-coated dog depends a great deal on how dirty he gets and how often you brush and comb him. Most people get by with a bath once a month, but this may vary.” Super thick dog coats may need fewer baths but more brushing to reduce shedding and keep coats shiny and healthy. These include; Finish Spitz, Husky, Great Pyrenees, ,mountain dogs and most Scandinavian breeds.
