Senior dog panting at night and restless: what to check first

Not veterinary advice: This article is for general information and isn’t a substitute for professional veterinary advice. Always talk with your veterinarian before changing your dog’s diet, supplements or medications, or if you notice new symptoms.

It’s 2 a.m., your older dog is panting beside the bed, and neither of you can settle. Here’s the short version: first check whether the breathing itself looks like an emergency, then check the room, then count your dog’s breaths while they rest. If the panting is new, keeps going, or comes with restlessness that’s different from your dog’s normal, call your vet. Pain, heart disease, hormone problems, airway disease and age-related changes in the brain can all show up this way, and only an exam can sort them out.

Key takeaways

• Check for emergency signs first: labored or noisy breathing, blue or pale gums, collapse, or a dog stretching out their head and neck to breathe.
• Count sleeping breaths. VCA Canada gives 15 to 30 breaths per minute as normal for a dog resting or sleeping. Rates that are consistently above 30 are considered abnormal.
• Night panting plus restlessness has many possible causes, including pain, heart disease, Cushing’s disease, laryngeal paralysis, heat and cognitive dysfunction.
• Don’t give human medicine. AAHA says never to give a pet pain medication without talking to your veterinarian.
• Write down what you see (when, how long, breath counts, a short video) so your vet has something to work with.

Step 1: Rule out an emergency

Start by looking at how your dog is breathing, not just how fast. Cornell’s Riney Canine Health Center lists these signs of respiratory distress: rapid breathing with the mouth open, bluish gums or muzzle, visible effort of the belly muscles to breathe, the head and neck stretched out, wheezing, snorting or whistling sounds, and weakness or collapse (Cornell: Recognizing and responding to canine respiratory distress). Cornell advises going to the nearest emergency hospital, calling ahead, and running the car’s air conditioning on the way.

AAHA’s pain-sign guide says labored breathing, or panting that seems out of context, calls for immediate veterinary attention (AAHA).

Call your vet or an emergency clinic right away if your dog collapses, has labored or noisy breathing, has pale or blue gums, a swollen or hard belly, sudden paralysis or inability to stand, a seizure, repeated vomiting, or hasn’t eaten or had water for 24 hours or more. This list isn’t complete. If something feels wrong, trust your instinct and call.

If none of that is happening and your dog is breathing quietly between pants, move on to step 2. Stay watchful, though, and don’t hesitate to call if things change.

Step 2: Check the room

Panting is how dogs cool down, so the simplest explanation is sometimes the right one. Cornell notes that dogs have sweat glands only on their paws and rely on panting to cool off, and that older and overweight dogs are at higher risk for heatstroke (Cornell: Heatstroke). Heavy panting is the first sign Cornell lists, followed by drooling, vomiting, diarrhea, weakness, confusion, seizures and collapse.

Ask yourself:

• Is the room warm or stuffy? Move your dog’s bed somewhere cooler and make sure water is available.
• Is the bed comfortable? Older dogs with sore joints can have trouble getting comfortable on thin or worn bedding. The AVMA lists orthopedic beds among helpful changes for arthritic dogs (AVMA).
• Is the floor slippery? If your dog struggles to stand up or settle, see our guide to a senior dog slipping on hardwood floors.
• Did anything change? A late dinner, a new schedule, visitors, a thunderstorm or a house move can unsettle some dogs. (That’s our practical observation, not a medical finding. If the panting doesn’t ease once things calm down, treat it as a sign worth checking.)
• Does your dog need to go out? An older dog who needs a bathroom break may pace and pant. A quick, calm trip outside rules that out.

If a cooler room and a bathroom break settle your dog completely and it doesn’t happen again, it may have been circumstantial. If it keeps happening, move on.

Step 3: Count the breaths

Quick answer: a normal resting or sleeping breathing rate for a dog is 15 to 30 breaths per minute, according to VCA Canada. Ask your vet whether a different number applies to your dog.

Counting is the single most useful thing you can do at home, and it takes one minute. VCA Canada explains how to do it:

1. Wait until your dog is resting quietly or asleep.
2. Watch the chest. One in-and-out movement is one breath.
3. Time 30 seconds and count the breaths, then multiply by two. (Or count for a full 60 seconds.)

According to VCA Canada, a normal resting or sleeping rate is between 15 and 30 breaths per minute, and rates that are consistently greater than 30 are increased and considered abnormal. It’s normal for rates to be much higher when a dog is hot, stressed or active.

The page says to count again a few times over the next couple of hours to see if the rate is consistently high. If it is, contact your veterinarian as soon as possible, and if there are other signs too, the page says that’s more urgent still. Your vet may also have a different threshold for your dog, so ask what number to watch for (VCA Canada: Home breathing rate evaluation).

Why this matters: VCA Canada calls a rising resting or sleeping breathing rate an important early clue that a dog may be developing heart failure. It also lists restlessness, agitation and difficulty finding a comfortable position, and sleeping in a different position (such as sitting up) as signs to report.

Step 4: Notice the pattern

Details help your vet narrow things down. Use this table to organize what you’ve seen. It isn’t a diagnosis. It’s a way to describe the pattern.

What could be behind it?

Pain, especially arthritis

AAHA’s dog pain checklist includes “pants excessively at rest,” “restless, pacing,” and “repeatedly gets up and lies down; can’t seem to get comfortable” (AAHA dog pain checklist). The AVMA lists stiffness, difficulty standing, and avoiding stairs, jumping and cars as arthritis signs (AVMA).

Many dogs hide pain well. Night can be when it shows, because there are no distractions and lying in one position can stiffen sore joints. (Again, that’s our plain-language explanation. Your vet can say what’s going on for your dog.)

The most important rule is from AAHA’s client handout: never give your dog pain medication without consulting your veterinarian (AAHA handout).

Cognitive dysfunction (dementia)

Changes in the sleep-wake cycle are often the first signs owners notice. Cornell describes many aging dogs developing “midnight walks” through the house, along with pacing, whining or barking (Cornell: Senior dog dementia). Cornell’s list of signs for cognitive dysfunction syndrome includes disorientation, changes in interaction, sleep changes, house-soiling, lower activity or restlessness and pacing, and anxiety (Cornell: Cognitive dysfunction syndrome).

AAHA’s 2023 senior care guidelines say about 14% to 22.5% of dogs older than 8 have age-related cognitive impairment, and that daytime sleeping with nighttime restlessness is among the most common signs. The guidelines also point out that cognitive dysfunction can be a diagnosis of exclusion: your vet does an exam, bloodwork and urinalysis, and considers pain and organ disease as other explanations first (AAHA).

That’s why we don’t suggest assuming “it’s just old age” or “it’s dementia.” The AVMA lists changes in sleep patterns among the signs of cognitive dysfunction, alongside disorientation, increased anxiety and wandering (AVMA). Your vet can help rule out other causes first.

Heart disease

Merck’s owner guide says signs of heart failure may appear at rest. Left-sided congestive heart failure often makes dogs breathe faster than healthy dogs, and coughing, difficulty breathing and tiring easily with exercise are the most common signs (Merck Veterinary Manual). Merck adds that your veterinarian may ask you to count your dog’s breaths while sleeping or resting to monitor for early heart failure, which is what step 3 above does.

Cushing’s disease

Merck’s guide lists panting among the common signs of Cushing disease (hyperadrenocorticism), which tends to occur in middle-aged to older dogs, along with increased thirst and urination, increased appetite, heat intolerance, lethargy, a pot belly and skin changes (Merck Veterinary Manual). If your dog is panting at night and has also been drinking and peeing more, tell your vet.

Laryngeal paralysis

Cornell describes laryngeal paralysis as most common in older large-breed dogs, especially Labradors. Signs include noisy or raspy breathing, excess panting, coughing, gagging, intolerance of exercise and heat, a change in the bark, and, in severe cases, blue gums or collapse. It can become a medical emergency, signs worsen with excitement, stress, exercise or hot humid weather, and diagnosis needs a veterinarian’s exam under sedation (Cornell: Laryngeal paralysis).

Other causes

Cornell’s respiratory distress guide also names tracheal collapse, fluid in the lungs, pneumonia and cancer as possible causes of breathing trouble, and notes that pain and anxiety can mimic respiratory disease. In other words, a visit to your vet is how you tell them apart.

What you can do tonight

While you’re waiting for an appointment with your vet, and if your dog isn’t in distress:

• Keep the room cool and quiet, with water within reach.
• Offer a comfortable, supportive bed, with traction underneath so your dog can stand up easily.
• Add a nightlight. Cornell suggests nightlights for dogs that roam at night so they can see clearly and are less likely to get stuck. It also suggests an extra walk before bed may help some dogs, with consistent routines and no moving of beds or furniture.
• Give a calm bathroom break and then settle back down.
• Don’t give human pain relievers or sleep aids. Ask your vet about safe options. (We don’t list drugs or doses, and neither should anyone online. Your vet knows your dog’s health.)
• Keep notes. Write down what time the panting began, how long it lasted, your breath counts, drinking and urination, appetite, and any other changes. A short phone video of the panting or pacing can be very useful. Cornell’s dementia guide suggests bringing your notes to the vet, with senior checkups at least every six months.

What your vet will likely do

Expect a physical exam, questions about your dog’s daily routine and night-time behavior, and, depending on what they find, tests such as bloodwork and a urinalysis (AAHA’s cognitive guidance mentions these). Heart, airway and hormone problems each have their own tests. For laryngeal paralysis, Cornell notes diagnosis needs an exam under sedation. Your vet will talk through what the findings mean and the right plan for your dog.

When to call your vet

Call your vet promptly (same day if you can) if your dog:

• Pants at night more than usual, or the panting is new and keeps happening
• Has a sleeping breathing rate consistently above 30 breaths per minute, or whatever number your vet gave you
• Paces, can’t get comfortable or keeps getting up and lying down
• Is awake and wandering at night, seems confused, or has new accidents
• Is drinking and urinating more than usual
• Is coughing, gagging or making raspy noises when they breathe
• Won’t eat, or has other changes, such as stiffness, weakness or weight loss

If you see any of the emergency signs in step 1, don’t wait for morning:

Call your vet or an emergency clinic right away if your dog collapses, has labored or noisy breathing, has pale or blue gums, a swollen or hard belly, sudden paralysis or inability to stand, a seizure, repeated vomiting, or hasn’t eaten or had water for 24 hours or more. This list isn’t complete. If something feels wrong, trust your instinct and call.

Frequently asked questions

Is it normal for a senior dog to pant at night?

Dogs pant to cool down and when excited or stressed. But panting at night with no obvious reason such as heat, particularly if it comes with restlessness, is worth mentioning to your vet. AAHA lists panting at rest and restlessness among signs of pain.

Why is my senior dog pacing at night?

Pacing, whining and “midnight walks” through the house are described by Cornell as common in aging dogs with cognitive changes, and AAHA lists “restless, pacing” among signs of pain. VCA Canada also lists restlessness and difficulty getting comfortable among heart-related signs. So a senior dog pacing at night has several possible causes. Work through the steps above and call your vet if it keeps happening.

Why is my senior dog restless at night but fine during the day?

Sleep-wake changes are among the most common early signs of cognitive dysfunction, according to Cornell and AAHA. Pain can also be more noticeable at night. Your vet can help tell the difference.

How many breaths per minute is normal for a sleeping dog?

VCA Canada gives 15 to 30 breaths per minute as normal for a dog resting or sleeping, with consistent rates over 30 considered increased. Count for 30 seconds and multiply by two. Ask your vet if they have a different number for your dog.

Could my dog’s panting mean heart disease?

It can. VCA Canada calls a rising resting or sleeping breathing rate an important early clue for heart failure. That doesn’t mean your dog has heart disease, but it’s a good reason to count breaths and call your vet if the rate stays high.

Can I give my dog something for pain or to help them sleep?

Not without your vet. AAHA says never to give pain medication without consulting a veterinarian, and human medicines can be dangerous for dogs.

Is my dog panting because of dementia?

It might be part of it, but panting alone doesn’t point to dementia, and cognitive dysfunction is generally diagnosed after other causes are ruled out (AAHA). Share what you see with your vet.

When should I go to an emergency clinic instead of waiting for morning?

If your dog has labored or noisy breathing, blue or pale gums, collapses, or shows signs of heatstroke, go now. Cornell advises calling ahead.

The bottom line

Night-time panting and restlessness in an older dog is a message, not a diagnosis. Check for emergency signs, cool and calm the room, count the breaths, write down what you see, and call your vet. Heart, hormone, airway, pain and brain-aging problems each have their own next steps once your vet identifies them, and the sooner you ask, the sooner you and your dog can both get some rest.
