Dogs have limited ways to communicate with their pet parents. Some dogs whine when they're anxious during severe thunderstorms, they bark loudly when delivery workers approach their front doors, and others thump their tails when they're happy to see their owners.
Unfortunately, most dogs can't tell their human companions when something is wrong with their bodies. Some pet parents don't know that there is something wrong with their fur babies until they behave abnormally. One such abnormal behavior is excessive licking. While not always serious, excessive licking is a sign that your dog may have an undiagnosed medical or behavioral condition.
