How can I tell if a dog has fleas?
assistant
To determine if your dog has fleas, look for signs of flea activity such as scratching, bites, or black specks on your pet's fur. You may also be able to see adult fleas or larvae, which look like small white worms, on your pet. In addition, try combing your pet with a flea comb, which will help you to identify fleas or flea dirt (flea droppings) on the animal's skin.
