They are annoying little creatures that make your dog’s life a living hell. They are responsible for causing allergies and skin infections in your dogs. This happens when the fleas start rapid reproduction due to the warmth of the summer months. Even if you are getting your dogs treated for fleas every month, it is a good idea to check them every week for improvements. Look on their tail and belly button for any signs of fleas. Even if you find just one flea, you must take immediate action.
