When an old dog begins circling, pacing, or wandering restlessly, it’s confusing and often frightening.
We outline the common causes of circling and pacing in old dogs, what you can do at home, and when to seek veterinary help.
Old Dog Circling and Pacing — Why It Happens
Old dogs circle and pace due to cognitive dysfunction, neurological disease, pain, anxiety, sensory loss, or organ decline affecting their comfort and orientation.
As dogs age, the brain changes, mobility decreases, and internal systems become less stable. These shifts can make a senior dog restless, confused, or unable to settle down.
Circling may be a sign of disorientation, while pacing often reflects discomfort or anxiety. Some causes are mild and manageable; others require urgent attention.
Recognizing the patterns behind this behavior helps you understand what your senior dog is experiencing and how to support them.
Old Dog Circling and Pacing: Common Causes
Canine Cognitive Dysfunction (Dog Dementia)
Cognitive dysfunction is the most common cause of circling and pacing in old dogs.
As the brain ages, neurons lose efficiency and communication slows.
This leads to memory loss, confusion, and difficulty processing the environment — resulting in repetitive movements.
Dogs with cognitive dysfunction often:
• Circle aimlessly
• Pace throughout the night
• Wander without purpose
• Appear “lost” in their own home
• Forget familiar routines
• Fail to respond to their name
Circling occurs because the dog loses sense of direction or gets “stuck” in a loop of repetitive movement. Pacing often reflects restlessness caused by mental confusion and disrupted sleep-wake cycles.
These symptoms gradually worsen without supportive care, but early management can slow progression.

Neurological Issues, Brain Tumors, or Stroke
Neurological decline is a major cause of circling and pacing in elderly dogs.
Brain tumors, strokes, and nerve damage can affect how the brain interprets movement, space, and balance.
Damage to one side of the brain often causes dogs to circle in a single direction — left or right — rather than wandering randomly.
Common neurological signs paired with circling include:
• Head tilt
• Uneven pupils
• Loss of balance
• Walking in tight circles
• Falling to one side
• Confusion or staring
Brain tumors often develop slowly, causing circling and pacing to increase with time.
Strokes, however, may trigger sudden onset circling with rapid disorientation.
Senior dogs are especially prone to neurological disease, and these conditions require prompt evaluation.
Vestibular Disease
Vestibular disease affects the inner ear and brain pathways responsible for balance.
Older dogs may suddenly:
• Circle repeatedly
• Pace nervously
• Tilt their head
• Fall over
• Show eye flicking (nystagmus)
The sensation is similar to extreme dizziness in humans.
Pacing occurs because dogs try to “walk off” the dizziness, while circling reflects their struggle to maintain balance on one side.
Most cases improve over several days, but some residual circling may remain in senior dogs.
Vestibular disease can look alarming, but many cases are treatable with supportive care.

Pain
Pain — especially chronic pain — can cause pacing and circling in old dogs. Arthritis, back problems, hip pain, abdominal pain, or discomfort from organ disease can make it difficult for senior dogs to lie down or stay still.
Instead, they pace, reposition constantly, or circle to find a comfortable spot.
You may notice:
• Slow, stiff walking
• Reluctance to lie down
• Restlessness at night
• Whining or panting
• Difficulty rising
Circling may reflect the dog’s attempt to ease joint pressure before lying down. Pacing occurs when they cannot settle due to soreness or internal discomfort (e.g., pancreatitis, liver issues, bloat, gas buildup).
Pain-related pacing is often worse at night and decreases when pain is treated.
Anxiety, Stress, or Confusion
Senior dogs become more emotionally sensitive as they age.
Anxiety often increases due to:
• Hearing loss
• Vision loss
• Cognitive decline
• Routine disruption
• Separation anxiety
• New environments
• Nighttime darkness
Anxious dogs pace around the home, pant, cling to owners, or wander nervously even when nothing obvious changed.
Circling may also become a repetitive coping behavior similar to “self-soothing.”
Older dogs experiencing anxiety may not show traditional signs like trembling — pacing is the primary indicator.
Liver or Kidney Decline (Toxin Buildup)
Advanced organ decline can cause toxin buildup in the bloodstream.
These toxins affect the brain, leading to:
• Disorientation
• Wandering
• Circling
• Pacing
• Staring
• Restlessness
• Irritability
The condition known as hepatic encephalopathy (liver) is well-known for causing pacing and circling in older dogs.
Dogs may seem mentally foggy, confused, or unable to follow familiar commands.
When circling is paired with vomiting, appetite loss, or weakness, metabolic disease may be the underlying cause.

What to Do If Your Old Dog Is Circling and Pacing
Observe your dog in a calm environment and take note of what triggers the behavior.
Does it happen mostly at night? After walking? When alone? After meals?
Try guiding your dog gently to a quiet area with soft lighting. Sometimes reduced noise and stimulation help them settle.
Use rugs or carpet runners to prevent slipping. Dogs with neurological or vestibular issues pace because they can’t gain footing.
Maintain a consistent daily routine. Predictability helps senior dogs feel more secure.
Offer calming support such as soft music, pheromone diffusers, or a comfortable resting space. Dogs with anxiety benefit greatly from soothing environments.
Provide hydration and small, easy-to-digest meals.
Dehydration and nausea make pacing and circling worse.
Encourage short walks and gentle movement. Exercise improves joint comfort and reduces anxious pacing.
If cognitive decline is suspected, enriching activities such as scent games or slow feeding can help maintain mental clarity.
Always document frequency and duration of circling or pacing. Patterns help your veterinarian identify the cause and adjust treatment.
When to Call or Visit Your Vet
You should seek veterinary attention if your old dog is circling or pacing and any of the following signs appear:
- If your dog is circling only in one direction, neurological issues may be present. This is especially important if the behavior is sudden.
- If your dog seems confused, stares at walls, or gets stuck in corners, cognitive dysfunction may be progressing. Early treatment can slow the decline.
- If circling is accompanied by head tilt, eye flicking, or imbalance, vestibular disease is likely. Prompt evaluation helps determine if treatment is needed.
- If pacing occurs at night and disrupts sleep, cognitive or anxiety-related decline may be increasing. Medication or supplements can offer relief.
- If your dog seems painful, reluctant to lie down, or cries during movement, arthritis or internal discomfort may be involved. Pain should never be ignored, especially in seniors.
- If vomiting, diarrhea, or weight loss accompany circling, organ disease may be contributing. These symptoms require testing.
- If circling or pacing begins suddenly or worsens quickly, do not wait. Sudden neurological signs often reflect urgent conditions.
Key Takeaway
Old dog circling and pacing can be caused by cognitive decline, neurological disease, pain, anxiety, or internal illness. While some causes are manageable, others require urgent attention.
By observing your dog closely, creating a calming environment, and seeking veterinary support when needed, you can help your senior dog stay comfortable, safe, and emotionally supported through their final years.
