Dog Behavioral Problems: Licking

Compulsive licking in dogs may be an indication of a medical condition, boredom, obsessive behavior, a vitamin or mineral deficiency or an allergy. According to the Merck Veterinary Manual, to be identified as "compulsive," licking must exceed a normal level of grooming or exploration, depart from regular behavior, get in the way of other activities (including eating) and be difficult to stop.

  1. Licking Body Parts

    • The primary causes of dogs licking their paws, genitals or other body parts are medical conditions (such as dermatitis), allergy or boredom. Dogs that spend long periods of time crated or in a run may develop the habit of licking their paws to keep themselves occupied. Licking of any body part can indicate an allergic reaction to food, the environment, household detergents or plants. Licking of a joint may mean pain from a medical condition such as arthritis, or licking of the genitals could indicate a bladder infection. If the licking is accompanied by or has resulted in hair loss, consult with a veterinarian to identify the reason and to ensure that the dog is not at risk of secondary infection.

    Licking Other Dogs

    • Licking other dogs is usually a sign of either submission or dominance. The dog's attitude may provide a clue as to which of these is accurate. If the licking seems to take the form of "grooming," the dog is showing submission to the dog that it is licking. If the licking appears forceful and determined, and the other dog does not resist, then the dog doing the licking is attempting to dominate the other dog. Occasionally, dogs that are very close may lick each other if a medical condition exists that can be identified by scent.

    Licking the Owner

    • Your dog may lick you out of affection and respect, which are the basis for grooming. In dog society such licking is the homage traditionally given to the pack leader. This type of licking is usually not compulsive and involves licking your hand or face once or twice, particularly during cuddles or when you arrive home. If the dog continues to lick you, especially in a specific area, then it may be that it enjoys the taste or scent of something on your skin, such as body lotion. If the licking appears forceful and qualifies as compulsive licking, it may be that the dog is trying to dominate you, and steps should be taken immediately to re-establish your position in the home.

    Licking Foreign Objects

    • Dogs that lick sand or dirt may be lacking in vitamins and minerals. If the licking is focused on floors, furniture and walls compulsively, the dog may be bored or suffering from Obsessive Compulsive Disorder (OCD). If the dog licks the same spot all the time, check to ensure that it isn't licking paintwork or something that is equally tasty and may contain harmful substances. Some paints may contain lead, which tastes sweet to dogs but is highly toxic.
