It is recommended that you bathe your dog as often as necessary however no more than once at week at maximum. A good rule of thumb for adult dogs is to give them a bath once per month with warm water and dog shampoo, for puppies we suggest not bathing them at all before 12 weeks old as before this time they should be getting groomed the appropriate amount by their mother. Of course these are all guidelines and in some cases you may need to wash your dog more frequently, for example if they getting in a muddy situation or are exposed to fleas, more regular bathing may be necessary.
