Generally speaking, a healthy dog with a short, smooth coat and no skin problems doesn't need to be bathed often. In most cases, dog baths are more for the benefit of their pet parents than for the dogs themselves. Even so, it's a good idea to bathe your pooch at least once every two to three months. Bathing your dog gives you an excellent opportunity to check them over for signs of skin problems or lumps that could indicate a more serious health issue.

In some cases, though, your dog could benefit from having baths on a more regular basis. Here are several factors to consider when deciding if you should increase your dog bath frequency.

Your Dog's Activity Level
If your dog is highly active and spends a lot of time outside, they'll probably need a bath more often — especially if they regularly swim or play in the dirt. Even if they're not prone to getting into messes, athletic dogs could need more frequent baths to control their odor.

Their Type of Coat or Skin
Long-haired and curly-haired dog breeds generally require more regular bathing and grooming to keep their coats from matting, says the American Kennel Club.  Recommends bathing these types of dogs at least once every four to six weeks, with regular brushing between baths to maintain the coat. Short-haired breeds such as Labrador retrievers can get away with infrequent bathing as long as they're healthy
What if your dog has no hair? Hairless breeds like the Chinese crested dog, who lack the skin protection a coat provides, need to be bathed weekly. Dogs who tend to have oily skin, like cocker spaniels and basset hounds, also benefit from more frequent baths to prevent oil buildup on their skin.
Allergies or Skin Problems
Some dogs suffer from allergies or skin conditions that may require regular bathing with medicated shampoo. In these cases, the right dog bath frequency will depend on the instructions provided by your veterinarian or groomer. Dogs with itchy skin may also find relief from regular baths with a colloidal oatmeal shampoo. Dogs who don't respond well to oral or topical parasite treatments might need regular baths to help keep fleas and ticks under control.

Your Health and Comfort

For example, if you're allergic to pet dander or if your pup tends to bring outdoor allergens into the house, regular baths to clean your pet's coat might help you breathe easier. And if your pooch is allowed on the furniture or into your bed, bathing at the first sign of stink will make them easier to live with.
