Excessive Licking in DogsWritten By hannah hollingerPublished: 06/15/2017Updated: 11/03/2021Veterinary reviewed by Dr. Linda Simon, MVB MRCVSWhat is Excessive Licking?Excessive licking is a compulsive behavior which can affect any dog, of either gender, of any age and of any breed.  While it is a behavior which can drive a pet parent crazy, it is not without its serious side.  While some canines who lick compulsively do so due to anxiety, there are also some underlying systemic causes which must be addressed to protect your pet.Excessive licking is the compulsive licking of any surface for a period of time which is longer than is needed for exploratory or investigative purposes.Please note, this article is not focused on dog's who lick their own skin obsessively, which tends to be due to a dermatitis.Youtube Play

Symptoms of Excessive Licking in DogsThe symptoms of excessive licking are precisely what the name suggests -- compulsive and extreme amounts of time spent licking and it can be virtually anything in sight or within reach.  Here are some things you might notice in this area:

• Excessive licking of air, your face, the furniture, his paws, other animals, his genitals, the tile, the carpet -- virtually everything within reach
• The licking is prolonged - It lasts longer than is required to explore or investigate the object
• The licking may begin intermittently and increase in frequency and intensity as time goes on
• Scratching and biting often accompany the excessive licking
• Hot spots, red and abraded areas that are painful

Types  There are two types of excessive licking categories:

• Licking of surfaces in his environment - This type is called Excessive Licking of Surfaces and can include anything and everything within reach in your canine family member’s world
• Self-licking - This type generally results in Acral Lick Dermatitis; it can begin as an allergic reaction or simply as a particular area that your canine family member just keeps licking, biting and chewing at until an abrasion or lesion is created which causes him to keep up the behavior. Of course, underlying medical issues such as atopic dermatitis and parasites must be ruled out if we are to confirm the diagnosis of a behavioral issue.

Causes of Excessive Licking in DogsThe excessive licking behavior in dogs has been, for many years, attributed to anxiety and stress release.  While this may be the case for some canines, recent research has suggested that gastrointestinal issues may actually be a major factor in the development of the behavior for many canines.  One such study was done in Montreal using 19 canines who were suffering from excessive licking of surfaces.  Fourteen (14) of the nineteen (19) were found to have gastrointestinal issues, like:

• Infiltration of lymphocytes and plasma cells and other inflammatory cells into gastrointestinal tissues

• Delayed gastric emptying

• Irritable bowel syndrome

• Chronic inflammation of the pancreas

• Gastric foreign body

• Giardiasis - an infection caused by the giardia parasite

Diagnosis of Excessive Licking in DogsSince this behavior could be behavioral or neurological as well as systemic, a multi-step diagnostic approach may be required by your veterinary professional.  Of course, your input will be very important as he assesses your family pet’s condition.  Your input will be needed regarding your pet’s dietary regimen, husbandry habits, health history and vaccinations (if that information is not readily available to the attending vet),  exercise routine and frequency, urinating and defecating habits and behaviors and any changes in any behaviors noted and the duration of those changes. Behavioral changes are generally a signal that your pet could be sick or that something is amiss in his life.  Your vet will perform a physical and neurological examination and will need to order some testing based on his findings in that examination. He will also need to do some testing to rule out as many of the systemic causes for any potential skin infections or deeper internal abnormalities as possible.  You should expect him to order blood testing, urine and fecal samples, perhaps tissue scrapings from abraded areas and even some imaging studies like x-ray, CT scanning or MRI studies.  Depending on his assessment, he may also need to order a behavioural review of your pet to assess any underlying anxiety. With the newer research into the gastrointestinal component, your vet may wish to do a gastric work up on your pet to look for those causes. It is important to note that, if your pet is licking carpet, furniture and other fibrous surfaces, he may be ingesting fibers and hairs which can cause digestive issues that can realist in intestinal blockages.  Your vet may wish to look into that possibility as well, especially if your dog is also showing signs such as weight loss or vomiting.Treatment of Excessive Licking in DogsOnce your veterinary professional has completed his assessment of your family pet, an appropriate treatment plan will be developed and initiated.  The treatment plan will, of course, be dependent upon the findings in the various examinations and testing of your pet.  If underlying systemic causes are found, expect that your vet’s primary concern will be to treat those underlying systemic diseases and conditions for the safety and health of your pet.  These steps might include:

• Administration of antibiotics for any bacterial infections found or antifungal medications for any fungal infections found
• Dietary changes if a food allergy is suspected.  This might include a commercial elimination diet to isolate the food component which is causing the problem
• Treatment of any parasitic infestation, infection or other parasitic involvement
• If a gastric foreign body is found, surgical removal may be necessary
• If a gastric blockage is found, surgical removal of the blockage will be required
• Exercise routine changes and environmental enrichment may be suggested for those canines found to be responding to built up anxiety and stress
• Some dogs may require prescription anxiolytic medicine
• Changes in grooming products or shampoos may be suggested if contact dermatitis is found
• Changes in household cleaning products may be required if contact dermatitis is suspected
• Hormonal supplementation may be required if a systemic hormonal imbalance is found
• Retraining of both the family pet as well as the family may also be required if the excessive licking is determined to be just a compulsive or attention-getting behavior

Recovery of Excessive Licking in DogsExcessive licking in dogs is definitely a health concern as well as an annoying behavior for pet parents.  If you have a canine family member who is afflicted with this behavior, it is important to understand that it may not completely go away forever.  If there is an underlying health condition which needs to be addressed, and that condition is addressed, then the prognosis is better for improvement in the behavior.  If it is determined to be a result of something in the environment or changes in home routines, the licking could be temporary if those ongoing recommendations aren’t continued.  The important point here is to get your family pet evaluated so that any underlying conditions are found and treated.Excessive licking could be a symptom of a serious medical condition. .

My pet has the following symptoms:LickingMy dog is constantly licking. It has increased in frequency over the past several months. It seems to get worse at night.

My pet has the following symptoms:Noisy BreathingMy female dog keeps excessively licking her crotch, and her bottom nipples seem puffy. What is causing her to lick her privates constantly.July 15, 2020Answered by Dr. Michele K. DVM0 RecommendationsThank you for your question. Your dog may be coming into heat, or she may have an infection. If this resolves in a few days, it is probably a heat cycle, and if that annoys you, it may be best to have her spayed. That will take away this possibility in the future. If the problem doesn't resolve, and she continues to lick herself, then she may have an infection, and it would be best to have her seen by a veterinarian. I hope that all goes well for her.July 15, 2020Was this question and answer helpful?
