Generally speaking, in summer, it is best to bathe your dog every 7-10 days, but in spring and autumn, when the temperature is relatively low, you can postpone the bathing to once every two weeks. If it is cold winter, , then the bathing interval can be extended to once a month or 20 days. If the dog is not particularly dirty, generally speaking, there is no need to bathe frequently, as this will damage the dog's hair follicles.
