How many times should you wash a dog?

How often to wash a dog depends on many factors, mainly based on coat type and lifestyle.
As a rule of thumb, a dog should not be washed more than once a week, unless under the supervision of a veterinarian because of a skin condition.
Be sure to use products designed specifically for your pet because the pH (acid) balance for dogs is different from that of humans.
And don’t wash your pet too often, as this can strip the skin and coat of useful natural oils.
