The increasing number of spots on the Bichon Frize may be caused by skin diseases, pigmentation, melanoma, sunburn, etc. Generally, it will not affect the health of the dog, but it is necessary to check whether the dog has skin diseases. Bathe your dog and deworm them on time. Do not shave when trimming your Bichon Frize, especially in summer. Otherwise, ultraviolet rays will directly irradiate the Bichon Frize's skin, which can easily cause sunburn, skin diseases, pigmentation, etc.
