Dogs, like people, need to bathe regularly. How often you wash your dog depends on several factors: the breed of dog, its age, whether it has been groomed recently, and how dirty it is. Dogs that live in hot climates or spend a lot of time playing outdoors may need to be bathed more often than those who don’t. So how often should you bathe your dog? Generally, most dogs should be given a bath every 1-2 months. However, some exceptions exist: puppies and elderly dogs may need less frequent baths, while dogs with thick fur coats may need more.
