Why Does My Dog Pace Back and Forth at Night?

I remember a 12-year-old Cavalier named Biscuit whose owner called me at nine at night because he’d been walking a tight oval around the coffee table for forty minutes straight, panting, refusing to lie down, and bumping the same corner of the ottoman twice. She’d tried a longer walk, a food puzzle, even leaving the TV on. Nothing touched it. What she was describing wasn’t restlessness in the way a young dog gets restless before a storm — it was a dog whose internal clock and comfort level had both come apart at once, and she had no way to tell which one to fix first.

That’s the trap with nighttime pacing. It looks like one behavior from the doorway, but it’s rarely one cause underneath. In my practice, I’ve learned to slow down before naming it “just anxiety” or “just old age,” because the treatment plan diverges hard depending on what’s actually driving it.

What’s Actually Going On When a Dog Won’t Settle After Dark?

Pacing at night is a dog’s nervous system telling you it can’t get comfortable enough, physically or mentally, to switch off. In younger, otherwise healthy dogs, this is usually anxiety-driven — noise sensitivity, separation distress that ramps up once the house goes quiet, or a change in routine. In senior dogs, the picture gets more crowded. Pacing that worsens specifically at night, rather than round-the-clock, points toward one of three overlapping culprits: chronic pain that’s harder to distract from once the house is still, a urinary or systemic issue causing genuine physical discomfort, or a shift in the sleep-wake cycle tied to cognitive aging.

None of those three respond to the same intervention, which is why I push owners to describe the pacing in detail rather than just naming it. Does the dog get “stuck” facing a wall or corner? Is there vocalizing that seems aimed at nothing? Does it track with slower rises from the couch or reluctance on stairs earlier in the day?

Could This Be Canine Cognitive Dysfunction?

If your dog is a senior and the pacing comes bundled with disorientation, staring blankly, house-training lapses, or a flipped sleep schedule — sleeping more by day and wandering more at night — canine cognitive dysfunction (CCD) belongs on the differential list. It’s an age-related neurodegenerative condition, and the AAHA Senior Care Guidelines for Dogs and Cats note that clinical signs are highly varied and include inactivity, inattention, anxiety, incontinence, wandering, and sleep-wake cycle disorder. A recent narrative review in the PMC (National Library of Medicine): Diagnosis of Canine Cognitive Dysfunction Syndrome paper puts the estimated prevalence at 14% to 35% of dogs over eight years old, and it stresses that management is most effective when it starts early.

I want to be direct about something, though: CCD is a diagnosis of exclusion. You don’t get there by skipping the exam.

Is It Pain Instead — And How Would You Even Tell?

This is where my TCVM training changes how I question an owner. Chronic pain, especially early osteoarthritis, doesn’t always show up as a limp. It shows up as a dog who can’t find a position that stays comfortable for more than a few minutes, so they get up, circle, resettle, and repeat — often worse at night because there’s less to distract from it and cooler joints stiffen further. I ask about stairs, about jumping onto the couch, about how a dog moves in the first few steps after a long nap versus after they’ve “warmed up.” A dog who paces at 2 a.m. but also hesitates before the back stairs at 7 a.m. is telling you something different than a dog who’s just disoriented.

One patient I still think about was a nine-year-old Labrador mix named Otto, brought in because he’d started pacing the hallway nightly around midnight, unable to settle on his bed even after his owner added a thicker orthopedic pad. What his owner hadn’t connected was that Otto had also stopped jumping into the car three weeks earlier, and his gait looked stiff for the first ten steps after getting up from a nap. Once we treated the underlying joint discomfort as part of a broader plan — acupuncture, weight management, and a joint-support routine alongside food therapy adjustments — the nighttime pacing eased over the following weeks. I don’t present that as a guarantee for every dog with similar signs; it’s one case, and pain in an aging dog is never treated in isolation from the rest of the picture.

Where Do Calming Ingredients Actually Fit In?

Once pain and cognitive change have been ruled in or out, some dogs are left with a nervous-system component that plain anxiety support can genuinely help — but I want to be precise about what “help” means here, because the evidence varies a lot by ingredient.

Chamomile has a long history in traditional herbal care used to support relaxation, and a recent review found that for most species, including dogs, the evidence is derived mainly from preclinical studies or traditional use rather than large controlled trials — meaning it may help maintain calm behavior in some dogs, but it isn’t a well-established clinical treatment (see the Biomedicines review on chamomile and anxiety/stress). Ashwagandha, particularly the KSM-66 extract, has firmer human-research footing: a systematic review published in Cureus analyzed multiple randomized controlled trials and concluded that ashwagandha has a moderate positive impact on stress reduction and cognitive performance — though that evidence base is human, not canine, so I treat it as supportive rather than definitive when I recommend it for a dog. L-theanine is an amino acid found in tea that’s been studied for calming properties, and a review in Molecular Psychiatry found a meaningful effect in one human anxiety study at 400 mg/day over eight weeks — again, human dosing that doesn’t map directly onto a dog’s needs.

Short version: these ingredients may support a calmer baseline. They don’t replace a workup, and none of them are a substitute for treating pain or diagnosing CCD.

So What Should You Actually Do Tonight?

Here’s the scene I keep coming back to. A client I worked with had a ten-year-old Beagle who’d started pacing every night around 1 a.m., pausing at the same spot by the kitchen doorway as if he’d forgotten why he walked there. She’d assumed it was “just getting old” for almost two months before bringing him in. By then he’d also lost some house-training reliability and seemed less interested in greeting her at the door — both signs she hadn’t connected to the pacing until we talked through the timeline together. We ran bloodwork to rule out systemic causes, checked his joints, and started a cognitive-support plan alongside environmental changes like nightlights and a more predictable bedtime routine. The pacing didn’t vanish overnight, but it became less frequent within a few weeks. I share that not as a formula but as a reminder: the timeline and the small details owners almost skip over — the doorway pause, the missed greeting — are usually where the real answer is hiding.

My verdict, for what it’s worth after years of working these cases: if your dog is a senior and nighttime pacing is new, don’t reach for a calming chew first. Get the exam. Rule out pain and systemic disease. If cognitive change is confirmed or suspected, start management early, because that’s when it works best. Calming ingredients like ashwagandha or L-theanine can be a reasonable piece of a broader plan once you know what you’re actually managing — but they’re a supporting player, not the diagnosis.

If your dog’s pacing is paired with panic-level anxiety rather than pain or confusion, it’s worth reading through what the evidence actually supports for dog anxiety supplements and how melatonin for dogs fits into a sleep-focused plan. And if the pacing seems to track with stiffness or reluctance to move, our breakdown of ashwagandha for dogs and this guide on a dog’s back legs giving out cover the mobility side of that picture in more depth.

Nighttime pacing isn’t a diagnosis you can make from the hallway. It’s a pattern worth writing down — when it starts, what it looks like, what else has changed — and bringing to an exam room before you decide what to treat.

So if you’re standing in the hallway tonight, watching your dog circle for the third time — what changed in the last few weeks that you haven’t mentioned to your vet yet?
