Why Is My Dog Restless Only at Night?

What You're Noticing

Your dog paces, circles, can't settle in one spot, whines, keeps coming to find you, or wakes repeatedly during the night. During daylight hours they seem fine — but when the household quiets down and the lights go off, the restlessness begins.

Why This Might Be Happening

Pain or physical discomfort

Pain is often more noticeable at rest than during movement. A dog with arthritis, joint pain, or other discomfort may be distracted enough during the day's activity that the pain doesn't dominate — but lying still at night removes that distraction. If your dog gets up and lies down repeatedly, stretches frequently, shifts position often, or is reluctant to settle in one spot, physical discomfort is a strong possibility worth discussing with a vet.

Cognitive dysfunction syndrome (CDS) — senior dogs

CDS is the canine equivalent of dementia. It's common in dogs over 10–11 years old and one of its most characteristic signs is a reversal or disruption of the normal sleep-wake cycle — dogs with CDS often sleep more during the day and are wakeful, confused, or anxious at night. Nighttime pacing, staring at walls, apparent disorientation, and increased vocalization at night are all typical. If your dog is older and this has been gradually developing, CDS is worth considering.

Anxiety

Night brings changes that are significant to an anxious dog: the household goes quiet, familiar sounds disappear, the human "pack" is largely inaccessible, and nighttime sounds (wildlife, distant traffic, other animals) are more prominent. A dog with generalized anxiety or separation-related anxiety may be significantly more activated at night for these reasons. Thunderstorm or noise phobia can also manifest nocturnally.

Insufficient daytime exercise

A dog that hasn't had enough physical and mental exercise is essentially not tired enough to sleep through the night. This is particularly common in young, high-energy breeds. The solution here is straightforwardly more exercise and enrichment during the day — a tired dog sleeps.

Gastrointestinal discomfort

Acid reflux, gas, and other GI issues can worsen when a dog lies down. A dog that is uncomfortable with nausea or abdominal pain at rest may get up, pace, eat grass, or be restless. This is often accompanied by lip licking, swallowing frequently, or attempting to eat non-food items.

Underlying medical conditions

Hypothyroidism, Cushing's disease, urinary tract infections (which cause urgency), kidney disease causing increased urination at night, heart conditions, and neurological problems can all disrupt sleep. If the restlessness came on without an obvious behavioral explanation, medical causes deserve consideration.

What to Check

• Age and history: New onset in a senior dog has different implications than in a young adult dog.
• Posture and movement: Does your dog seem uncomfortable when they try to lie down? Do they get up and reposition frequently?
• Daytime activity level: Is your dog genuinely tired from exercise, or have they been mostly resting?
• Other symptoms: Increased thirst, urination, appetite changes, weight changes — these point toward medical causes.
• What happens when you engage them: Does the restlessness stop when you're present, suggesting anxiety? Or does it continue regardless?

What You Can Do

• For young/energetic dogs: Increase exercise meaningfully and add mental enrichment (puzzle feeders, training, sniff walks).
• For anxious dogs: Consider white noise, a calming dog bed, or a dog-appeasing pheromone diffuser. Keep the pre-bedtime routine calm and consistent.
• For comfort: Ensure the sleeping area has good orthopedic support, especially for older dogs.
• If you suspect pain or CDS: Talk to your vet — pain management and specific CDS interventions can make a significant difference.
