The black spots that can be squeezed out of the dog's pores may be caused by fleas laying eggs on the dog's body. They cannot be washed away and need to be squeezed out to clean them. Dogs need to be bathed and dewormed regularly, bathing twice a month and deworming once a month. Pay attention to the dog's hygiene to avoid the production of parasites, bacteria and fungi, and do not take the dog to dirty places. Environment, disinfect the environment regularly.
