Black particles on the dog

Black particles on the dog may be fleas. You can put the black particles on a paper towel and drip water to check. If it turns red, it means there are fleas, and the dog should be dewormed externally in time. Be careful to use deworming medicine specifically for pets, not for humans, to avoid allergies or side effects. Remove the dog's hair and drop it on the skin. Don't let go of the dog immediately after dropping the medicine. Let the medicine penetrate into the skin before letting go. When deworming your dog, be careful not to apply it to areas that your dog can lick.
