The simple answer to this question of how often to bathe a dog is: how often do you want to bathe your dog? Unless a dog has skin problems, there is no specific need to bathe the dog except to make him a more enjoyable companion.

like people, some dogs get stinky faster than others. I have known dogs
that have never had a bath in their life and do not have an unpleasant
smell, but my own dogs get bathed weekly.
