The frequency of bathing a dog depends on several factors including the dog's activity level, coat type, skin condition, and lifestyle. Here is a summary based on expert advice:

• General guideline: Most dogs do well with a bath about once a month. However, this can range from once every few months for less active or indoor dogs to every couple of weeks for very active dogs

• Activity level: Active dogs that get dirty or sweaty often need more frequent baths, about every two weeks or after particularly dirty activities like swimming or rolling in mud

• Coat type: Medium and long-coated dogs generally require bathing every 4 to 6 weeks to remove dirt and debris, while short-coated dogs may only need a bath every 1 to 3 months

• Skin condition: Dogs with sensitive or dry skin should not be bathed too often, as frequent bathing can strip natural oils and cause irritation. Weekly baths are possible but not usually recommended unless necessary

• Indoor dogs: Dogs that spend most of their time indoors and stay clean typically need baths less frequently, around every 4 to 8 weeks

• Puppies: Should not be bathed daily; only when necessary due to their delicate skin and developing coat

In summary, a good rule of thumb is to bathe your dog when they are dirty or smelly, roughly every 4 to 6 weeks for most dogs, adjusting based on their lifestyle and coat. Over-bathing can cause skin problems, so it’s important to balance cleanliness with skin health

Activity level should be the prime factor in determining how often you bathe your dog, says a professional groomer

Frequent bathing can be harmful if it strips oils from the skin, so use a quality shampoo and consult your vet if unsure
