Dog Circling Causes: When to Worry and See a Vet

Observing a dog that turns in circles just a couple of times prior to settling into a cozy position on its bed is typically not a cause for alarm.

When you notice your dog pacing in repetitive circles, this behavior could signify a range of possibilities, spanning from natural nesting routines to serious indicators of neurological issues. It is crucial to assess the full context of your dog's daily life and behaviors, particularly determining the appropriate moment to seek veterinary care for her.

Seeing an older dog meandering in circles can evoke both affection and worry in equal measure. The sight of a dog seemingly tamping down an imaginary bedding area harkens back to its wild forebears. However, once this deliberate circling evolves into a frenzied, ongoing, or unidirectional path, the explanation shifts from innate instincts to potential physical or anatomical concerns. To discern the boundary between normalcy and trouble, it helps to delve into the mechanics of a dog's innate sense of direction and the workings of its brain.

From the viewpoint of a veterinary neurologist, circling represents a multifaceted behavior whose interpretation hinges entirely on the surrounding circumstances. Many dogs naturally perform a few turns before reclining, a habit widely regarded as an instinctive nesting ritual, notes Christian Woelfel, DVM, a specialist in veterinary neurology at Garden State Veterinary Services.

That said, Dr. Woelfel emphasizes that persistent or frequent circling, especially when it adheres strictly to one direction, often points to an underlying neurological disorder affecting either the brain or the vestibular system, which serves as the central hub for balance within the nervous system.

Diagnosing Cognitive Dysfunction Syndrome

In older dogs, this circling tendency might manifest as an early warning sign of cognitive dysfunction syndrome (CDS). As outlined by Cornell University’s College of Veterinary Medicine, CDS constitutes a prevalent age-linked ailment in canines that impairs brain function, leading to progressive decline akin to human Alzheimer’s disease.

Symptoms of CDS can emerge as early as around 9 years of age. The condition frequently goes undiagnosed because its behavioral shifts develop gradually, leading many pet owners to dismiss them as inevitable aspects of the aging process, per the Cornell analysis.

Dr. Woelfel explains that brain-related conditions often present with supplementary symptoms like confusion, alterations in demeanor, impaired vision, and even seizures. In contrast, vestibular disturbances, which resemble human vertigo, typically feature circling alongside a tilted head, unsteadiness, rapid involuntary eye movements known as nystagmus, and signs of queasiness.

When Circling Is Just Circling

Not every instance of circling stems from brain-related problems; sometimes, it relates to the body’s efforts to achieve a more comfortable posture for various physical reasons. Inner ear infections, for example, can disrupt balance and prompt circling since the inner ear plays a pivotal role in regulating a dog’s equilibrium, according to Dr. Chyrle Bonk, a veterinarian practicing in Idaho.

Certain dogs develop a habit of making a few turns before settling down to rest or before defecating. This pattern usually serves merely as their method of finding comfort and has integrated into their regular routine, Dr. Bonk observes.

She highlights that canine anxiety can closely resemble CDS symptoms. The key differentiator lies in anxiety’s situational nature: it might flare up due to your departure for work, the arrival of unfamiliar guests, or disruptions in the home environment, whereas CDS indicators persist consistently or intensify particularly at night.

Dr. Bonk describes pre-lying circling as an evolutionary holdover where dogs pat down an area to fashion a secure and plush resting spot. It might also function to sweep away potential hazards from the vicinity. Nevertheless, it warrants attention as a potential marker of health issues. Discomfort arising from spinal problems or hip dysplasia can render the acts of lying down and rising painful, prompting dogs to circle repeatedly in search of the optimal angle to settle without aggravating their pain.

When Should You Alert Your Vet?

A few preparatory turns before reclining or eliminating remain standard for the majority of dogs, Dr. Bonk affirms. However, reach out to your veterinarian promptly if the circling emerges abruptly, occurs during unrelated activities, or accompanies symptoms such as lack of coordination, heightened anxiety, indications of pain, bewilderment, disrupted sleep cycles, or unusual conduct.

Dr. Woelfel agrees wholeheartedly, stressing that sudden circling, particularly when coupled with additional neurological symptoms, merits an immediate visit to a general veterinarian or a specialized veterinary neurologist.

These neurologists possess expertise in nervous system disorders and excel at identifying the root cause of such circling behaviors while outlining precise diagnostic procedures and tailored treatment plans.

Checklist: When to Call the Vet

Prior to scheduling a vet appointment, systematically check your dog for potential circling triggers stemming from everyday physical factors. Nonetheless, initiate contact with your veterinarian if your dog matches any of the following criteria, drawn from insights by the American College of Veterinary Internal Medicine, Cornell University College of Veterinary Medicine, UC Davis Veterinary Medical Teaching Hospital, the International Association of Animal Behavior Consultants, and the American Animal Hospital Association:

• Sudden Onset: The circling behavior appeared abruptly, overnight.
• One-Way Street: Your dog consistently rotates in a single direction only.
• Nystagmus: Noticeable flickering or rapid side-to-side eye movements in your dog.
• Circles With No Purpose: The dog circles without intent to nest, appearing trapped or disoriented in tight spaces like corners.
• Physical Distress: Occurs in tandem with head tilting, vomiting tendencies, or vocalizations of discomfort during attempts to rest.

By vigilantly monitoring these patterns and acting decisively on concerning signs, you empower yourself to safeguard your dog's health and well-being effectively. Early intervention often leads to better outcomes, allowing your furry friend to resume a joyful, active lifestyle.
