My dog has been scratching a lot lately. What could it be?

It is possible your dog may have fleas, which can cause excessive scratching and biting. You should check for any signs of fleas such as small black dots on the skin or fur, or tiny red spots that appear after being bitten by an adult flea. If you find these signs, you should treat your pet with an appropriate flea treatment to help alleviate the problem.
