Don’t Shame Your Dog for This Odd Behavior, This Is Far More Effective

Analysis by Dr. Karen Shaw Becker

obsessive compulsive disorder in dogs

Story at-a-glance -

  • Canine compulsive disorder (CCD), which is similar in many ways to obsessive-compulsive disorder in humans, is relatively common due in part to modern-day lifestyles
  • CCD behaviors include tail chasing or spinning, excessive licking, chasing lights or shadows, and fly snapping, and chasing after or pouncing on invisible prey
  • Dogs with CCD and humans with OCD share a number of traits involving both biological and environmental influences
  • Dogs with repetitive behaviors should be examined by a veterinarian first to rule out underlying medical conditions
  • The right diet, a “job” or hobby, lots of physical activity, environmental enrichment and other strategies can be extremely beneficial in the management of dogs with CCD

Dogs with compulsive disorders are relatively common, and unfortunately, this is due in large part to modern-day lifestyles. As much as we love our four-legged family members and try to provide for all their needs, most of us aren’t in a position to allow them to live according to their true canine natures. If they could make their own choices, our dogs would be extremely active, spending lots and lots of time outdoors.

Canine Compulsive Disorder

Canine compulsive disorder (CCD), also called compulsive behavior disorder, is similar to obsessive-compulsive disorder (OCD) in humans. People with OCD perform repetitive activities (e.g., washing their hands over and over) and can't seem to control the behavior.

Compulsive behavior disorder in dogs is also characterized by the repetitive performance of behaviors that serve no purpose. These behaviors include tail chasing or spinning, excessive licking or self-mutilation, flank sucking, chasing lights or shadows, fly snapping and chasing after or pouncing on invisible prey.

CCD shouldn’t be confused with similar repetitive behaviors some healthy, well-balanced dogs perform. For example, herding dogs and other working breeds evolved to do jobs that require the same behavior over and over again. Many retrievers will fetch the ball from sunrise to sunset; other dogs spin in happy circles when they’re excited.

There are also dogs who fixate on smaller animals such as lizards or birds, or inanimate objects like rocks or golf balls. Bored dogs also tend to develop habits that might seem compulsive, such as running along the fence in the front or backyard, or gently licking and chewing a particular paw.

As with humans with OCD, the favored behavior of dogs with CCD can take them over to the point that it interferes with normal daily activities like mealtime and playing. It can also be difficult to interrupt the compulsive behavior once the dog begins performing it.

Research Compares CCD in Dogs and OCD in People

Two of the most common repetitive behaviors in dogs are obsessive licking which results in acral lick dermatitis (ALD), also known as a lick granuloma, and tail chasing. A 2012 Finnish study suggests that dogs exhibiting indicators like tail chasing, air biting (fly snapping), obsessive pacing, trance-like freezing, or licking or biting their own flanks do indeed have a disorder similar to OCD in humans.1 A number of features of tail-chasing dogs are similar to obsessive-compulsive humans, including:

  • People with OCD and tail-chasing dogs begin acting out their behaviors at a young age
  • Both are inclined to engage in more than one compulsive activity
  • Nutritional supplements (vitamins and minerals) are beneficial in reducing the behaviors in both people and dogs
  • OCD is linked to childhood trauma and stress; tail chasing is seen more often in dogs who were separated too early from their mothers
  • Certain people with OCD are on the shy, inhibited side, and this tendency is also seen in tail-chasing dogs

In addition to these similarities, a team of researchers including veterinary behaviorist Dr. Nicholas Dodman, professor emeritus at Tufts University and the Cummings School of Veterinary Medicine, performed MRI scans on a group of Doberman Pinschers (a breed predisposed to repetitive behaviors), half with acral licking and half without.2

“When we scanned the Dobermans with acral licking, we found they had sophisticated, minute details in the brain that are also found in humans suffering from OCD,” Dodman told veterinary journal dvm360. “The changes were, if not identical, compellingly similar.”3

The Doberman study also revealed a genetic component to CCD. “We … found a gene called CDH2, otherwise known as neural cadherin (NCAD), expressed most significantly in dogs with the compulsive problem,” explains Dodman. Following Dodman’s study, psychiatrists in South Africa discovered that the same deformation of CDH2 was found in humans with OCD.4

Important Considerations for Dogs With Compulsive Behaviors

If you suspect your dog is developing a compulsive disorder, I strongly encourage you to take her to your veterinarian for a wellness exam to ensure the source of the repetitive behavior is indeed behavioral and not an underlying physical condition that needs to be identified and addressed.

The sooner strange behavior stemming from CCD (and diseases causing behaviors that mimic CCD) is addressed, the sooner you can intervene and help. For example, there are lots of reasons dogs lick certain areas of their bodies, many of which can involve allergies and/or skin disorders. It’s important to rule out a problem that actually started in the body rather than CCD, which starts in the head. Other steps you can take to help a dog with CCD:

  • Feed a nutritionally balanced, species-appropriate diet that provides everything your dog needs and nothing she doesn’t (e.g., dyes, preservatives, artificial flavors, synthetic nutrients).
  • Ensure she’s getting daily (and sometimes twice a day, depending on the dog), consistent, rigorous exercise that promotes good muscle tone and body weight, and provides for a strong and resilient musculoskeletal system and organ systems. Exercise releases “feel good” hormones dogs benefit from on a daily basis.
  • Find a hobby or “job” she really enjoys (my personal favorite is K9 nose work).
  • Limit exposure to EMFs in your home by turning off the wireless router at night and providing a grounding pad.
  • Ensure your dog’s immune system is balanced and optimally functional and titer test, in lieu of potentially over-vaccinating.

Most dogs today aren't nearly as physically active as they're designed to be. It can be a challenge to tire out a big or high-energy pet, especially a working or sporting breed. If your dog is performing compulsive behaviors, try increasing her exercise. Some suggestions:

Walking or hiking

Jogging

Swimming

Obedience or nose work events

Playing fetch or tug-of-war

Flyball

Biking with a special dog bike leash

Agility or other canine sports

I also recommend helping your dog stay mentally stimulated with chews and treat-release toys. In my experience, there are very few extremely healthy, physically active dogs with intractable compulsive disorders, so I can't overstate the importance of helping your dog be as healthy and active as possible.

Additional Recommendations

Dogs with compulsive disorders tend to be more anxious and high strung than other dogs. An anxious nature may be inherited, but studies suggest environment also plays a role in triggering the expression of a compulsive behavior. Dr. Dodman makes the point that environmental enrichment by itself probably won’t resolve a compulsive disorder, but a stress-free, enriched environment can prevent CCD in the first place and make relapse less likely after a dog has been successfully treated.5

Veterinarians often treat dogs with CCD with drugs that block opioid receptors, but needless to say, I'm not in favor of jumping immediately to pharmaceuticals to treat this condition. They are sometimes appropriate in extreme, intractable cases (for example, a dog headed for the shelter) or when an animal is causing harm to himself.

They can also be beneficial as an interim measure to interrupt the cycle of behavior at the same time other less harmful remedies are being attempted. But my general recommendation is to try behavior modification along with a wide variety of natural remedies first, since every drug has side effects.

In a recent post in the Whole Dog Journal, professional trainer Mardi Richmond discusses additional treatment strategies such as avoiding known triggers, interrupting and redirecting the compulsive behavior, teaching an alternative response, and creating a structured daily routine (to reduce stress).

It’s also important not to try to prevent a dog from performing a repetitive behavior with physical restraint, because it typically causes more anxiety, not less.
