Why Is My Old Dog Restless at Night? Pacing, Panting and Waking Explained

It's 2am, and your old friend is wandering the house — panting, clicking across the floor, unable to settle. It's hard to watch, and it's exhausting for both of you. The good news is that night restlessness in older dogs usually has a cause, and many of those causes can be treated or eased.

Why Older Dogs Get Restless at Night

Night is when problems show up. During the day, a dog is distracted. At night, with the house quiet, pain and confusion are harder to ignore. These are the most common reasons:

Pacing in an older dog can also be a sign of neurological problems, inner-ear balance problems, or other illness. Purina's veterinary guidance is direct about it: when you notice an old dog pacing, get them checked by a vet.

Signs of Canine Cognitive Dysfunction

Canine cognitive dysfunction is an age-related decline in brain function — sometimes called "dog dementia." A flipped sleep schedule, sleeping all day and restless at night, is one of the classic signs. Others vets look for include (PetMD):

• Disorientation: getting lost in familiar rooms, standing at the wrong side of a door, staring into space
• Changes in interactions: less interest in family, or suddenly much more clingy
• Sleep-wake changes: awake and wandering at night, sleeping more in the day
• House-training lapses: accidents from a dog who was reliably trained
• Activity changes: aimless pacing or circling, or much less play
• Anxiety: new fears, restlessness, vocalizing at night

If several of these sound familiar, tell your vet. There's no cure, but there are things that can help — including diet, enrichment, routine, and medications your vet may suggest — and other conditions need to be ruled out first. The Morris Animal Foundation publishes a checklist you can fill in before the appointment.

What You Can Do Tonight

These won't replace a vet visit, but they make nights easier while you figure out the cause.

1. Make the bed easier on old joints

A thin cushion on a hard floor is hard on arthritic hips. A thick, supportive orthopedic bed lets a stiff dog get comfortable and stay comfortable. Put it somewhere warm, out of drafts, and on a rug if your floors are slippery. See our guide to orthopedic beds for older dogs.

2. Move the last potty trip later

Take your dog out right before you go to bed, not an hour before. Older dogs often need to go more often. If they're waking to go out and drinking much more than usual, mention it to your vet.

3. Add a soft night light

Dim, steady light in the hallway and near the dog bed helps dogs with poor eyesight or nighttime confusion get their bearings. Plug-in dusk-to-dawn lights work well.

4. Keep the routine predictable

Same dinner time, same evening walk, same bedtime. Predictability matters more as dogs age — especially for dogs with cognitive changes.

5. Tire the mind during the day

Gentle sniff walks, food puzzles, and short training games during the day help many older dogs sleep better at night. Aim for a calm, engaged day — not exhaustion.

6. Let them sleep near you

Many older dogs settle better within sight or smell of their people. If your dog has always slept alone, try moving their bed into your room for a while.

What Not to Do

• Don't give human pain medicine. Ibuprofen, acetaminophen, and aspirin can be dangerous for dogs. Only use what your vet prescribes.
• Don't scold accidents or night wandering. It isn't misbehavior, and stress makes both worse.
• Don't assume it's "just old age." Many causes of night restlessness are treatable, and pain is often underestimated in older dogs.

When It's an Emergency

Call your vet or an emergency clinic right away if your dog:

• Pants heavily at rest, especially with a swollen or tight belly, retching without bringing anything up, or restlessness (possible bloat in large dogs)
• Collapses, has a seizure, or can't stand
• Has trouble breathing, pale gums, or seems to be in severe pain
• Strains to pee and nothing comes out

Frequently Asked Questions

Why does my senior dog pace at night?

Common causes include pain (often arthritis), needing to pee more often, age-related cognitive changes, vision loss, anxiety, and itchy skin. Pacing can also signal neurological or other medical problems, so a new pacing habit in an older dog is worth a vet visit.

Why is my old dog panting at night?

Panting at night can be caused by pain, anxiety, being too warm, heart or breathing problems, or other illness. If your dog is panting heavily at rest, seems distressed, or has a swollen belly, treat it as an emergency.

Is it dementia if my old dog is awake at night?

It can be. A reversed sleep schedule — awake at night, asleep during the day — is a common sign of canine cognitive dysfunction. But pain and other medical problems cause the same thing, so your vet will want to rule those out.

What can I give my old dog to help them sleep?

Start with comfort and routine: a supportive bed, a late potty trip, a night light, and a predictable evening. Don't give human sleep aids or pain medicines. If your dog still can't settle, ask your vet — they can recommend treatments for pain, anxiety, or cognitive changes that are safe for your dog.
