Why Does My Dog Lick So Much?

yorkshire-terrier-343198_960_720Obviously, dogs can’t verbalize how they are feeling to us beyond perhaps a bit of whining or barking, and that’s pretty non-specific and really difficult to interpret. If you have a pup that licks a lot, you might be left wondering why.

There are many cases where/what your dog is licking can give you an idea that something localized and specific is bothering him or her. If your dog is licking between his or her toes, for example, it would be logical to check that area to see if there is a burr, a splinter or a sore that he is worrying. If your pup is licking his or her tail, or the base of his or her rump, you may consider a flea problem or an anal gland irritation. Additionally, sometimes your dog licks your face in greeting or licks your arms just because.

However, you may be wondering what does it mean if you don’t see any logical reason for your dog to be licking and/or is persistently licking either himself or inanimate objects, floors, carpets, toys or seemingly nothing at all? This article will discuss a few reasons why a dog may be licking so much.

Reasons Why Your Dog May Be Licking Excessively

Something Hurts

This is not always something obvious, such as the burr between the toes. Your pup may be licking because of inflammation or infection in the skin, arthritis pain in a joint or even a tingling or numb sensation for a nerve problem.


If you think about it, when your stomach is hurting you tend to get a bad taste in your mouth or you produce a bit of excess saliva that can make you swallow or lick your lips. This is also the case for dogs, in which case any underlying disorder that produces nausea could cause your dog to lick a lot.

Hunger or Dehydration

Being hungry or having a dry mouth can also result in increase licking in your dog.

Dental Disease, Oral Lesion or Foreign Object

Anything painful or abnormal in your pup’s mouth could make him lick excessively as well.

Neurological Problems

When dogs seizure, for example, they don’t always have full-blown, whole body, grand mal seizures. Sometimes seizures can be very localized twitches. Thankfully, we don’t see many dogs with canine distemper virus infections anymore, but when dogs are infected, they can develop systems commonly (and aptly) called “chewing gum fits.”

Cognitive Dysfunction

Older dogs that develop dementia can present for excessive licking.

Obsessive Compulsive Disorder

It is not uncommon for dogs to develop excessive licking (even to the point of producing physical trauma to their skin – i.e. lick granuloma lesions). This can occur for a variety of psychological reasons, including:

  • Stress
  • Anxiety
  • Separation
  • Boredom
  • Etc.

How Do You Know What’s Making Your Dog Lick?

As you can imagine, this may not be easy to diagnose. Over time, however, a behavior that might have been transient could become habitual and thus much more difficult to stop. Therefore, you should attempt to determine the cause as soon as the problem becomes apparent.

Your veterinarian will want to receive a very thorough history of the issue and make as question such as:

  • When did it start?
  • When does it happen?
  • How long does it go on?
  • Can you easily distract/stop the behavior?
  • If you stop it, does he go right back to licking?
  • Can you determine if the dog engages in the behavior when no one is there to see it by videotaping your when he is left alone.

You will also want to make sure to mention any other clinical or behavioral changes you have noticed in your dog, in case they are related — from personality or activity changes to changes in diet, appetite or water intake. Lastly, make sure to consider whether anything has changed in your dog’s environment that might be upsetting him or her, such as:

  • Did someone move away?
  • Did someone move back?
  • Is there construction going on next door?

Your veterinarian will need to do a complete workup to rule out the physical/metabolic reasons for excessive licking. A complete physical examination and laboratory testing will also be able to rule out those causes that can be identified.

How Do You Stop Your Dog From Licking?

If an underlying medical disorder is found, specific treatment will be prepared to address that issue. If stress, boredom or something environmental is the presumed cause then your veterinarian will discuss ways to decrease your dog’s anxiety and/or increase his comfort/happiness. Behavioral modification or the administration of mood enhancing medications may also be prescribed.


It is important to keep in mind that excessive licking can be an extremely complex and frustrating problem to resolve. You may even need to seek the assistance of a veterinarian specifically trained in animal behavior. Regardless, you and your veterinarian need to be partners in finding a diagnosis, creating a plan and then taking the time to patiently carry that plan through.
