Is Your Old Friend Trying to Catch Their Breath?

STORY AT-A-GLANCE

• November is Senior Pet Care Awareness Month, which makes it the perfect time to check your pet’s breathing, and loop in your vet at the first subtle change
• A healthy dog at rest breathes between 15 and 30 times per minute — anything consistently above 30 at rest (laying down quietly or sleeping) in a cool and calm environment, is outside the normal range and warrants attention
• Heart disease is the leading cause of respiratory difficulty in older dogs, with veterinary cardiology estimating up to 10% of dogs in general practice have some form of heart disease, especially older small breed dogs
• Tracheal collapse is a common cause in older small breed dogs causing coughing after excitement or after drinking water
• Red flags for immediate emergency care include blue, purple, or white gums, open-mouth breathing at rest, extended-neck posture, collapse, or coughing up pink frothy fluid

November is Senior Pet Care Awareness Month, which makes this the right moment to pay attention to changes in your senior pets. One of the most important signals the body can send is rapid or labored breathing — unfortunately, it’s also one of the easiest to brush off as "just aging."

Breathing changes in a senior dog are a red flag. They point to conditions that are often treatable when caught early, but dangerous when left alone. Keep reading to learn more.

Why Age Changes the Breathing Picture

Your dog's heart, lungs, and vascular system all experience some degree of functional decline with age. Conditions that accumulate and worsen over years, like heart valve disease, pulmonary fibrosis, chronic anemia, and laryngeal nerve degeneration, become far more prevalent in older dogs and the first sign may be changes in breathing. A 7-year-old dog breathing faster than usual is more likely to have an underlying medical cause than a 2-year-old dog, and the range of explanations are broader and more serious.¹

The same change in a younger dog might just be excitement or anxiety. In an older dog, it's a signal worth investigating. And because the systems involved — heart, lungs, airways, and circulatory system — tend to decline gradually rather than suddenly, the earliest signs are often subtle enough that a pet parent might shrug them off. So, if your senior dog is breathing differently, there's usually a reason.

What Normal Looks Like

A healthy dog at rest breathes between 15 and 30 times per minute.² Anything consistently above 30 at rest, in a cool and calm environment, is outside the normal range and warrants attention. Counting your dog's breaths per minute while they're settled is one of the most useful numbers you can give your vet.

Beyond rate, the character of breathing matters. Normal breathing is quiet, effortless, and rhythmic. Breathing that's audibly labored, accompanied by visible chest or abdominal movement, extended neck posture, open mouth at rest, or unusual sounds like wheezing, crackling, roaring, or rasping is abnormal regardless of the rate. If you are concerned it may help to take a video of your pet’s breathing — including how their chest is moving and abnormal neck posture or coughing — to show your vet.

The Common Culprits in Senior Dogs

A handful of conditions show up repeatedly in older dogs with breathing changes. Knowing them helps you connect what you're seeing to what might be going on:^3,4

• Heart disease — The leading cause of respiratory difficulty in older dogs. Veterinary cardiology estimates that up to 10% of dogs seen in general practice have some form of heart disease, with older small breed dogs at highest risk.⁵ As the heart's ability to pump efficiently declines, fluid can accumulate in the lungs (pulmonary edema), restricting oxygen exchange. Signs include a soft cough that gradually worsens, reduced exercise tolerance, a cough that wakes your dog from sleep, and reluctance to lie flat or on their back (dogs often sleep sitting up or in a position that opens their chest).
• Tracheal collapse — This is a common condition that affects mostly small breed dogs including Pomeranians, Chihuahuas, Toy Poodles, and Yorkshire Terriers, as well as many other breeds. It often worsens with age as the tracheal cartilage deteriorates. The classic sign is a goose-honk cough triggered by excitement, pulling on a collar, or drinking water. There is herbal therapy available to treat this as well as supplements to support the tracheal cartilage and medication for severe cases.
• Laryngeal paralysis — Another common cause of breathing changes, this is particularly common in large breeds such as Labrador Retrievers and Lab mixes. The arytenoid cartilages that normally open the airway during inhalation become paralyzed due to degeneration of nerves and stay partly closed. The telltale sound is loud, raspy, honking, or roaring inhalation.
  
  Dogs may become reluctant to exercise, gag, and bring up foamy liquid — and some may even develop aspiration pneumonia. Symptoms may worsen in warm or humid weather. In advanced cases, the gums can turn blue from oxygen deprivation. Treatment options include acupuncture treatment for mild cases as well as surgery to “tie back” the paralyzed cartilage and open the airway.⁶
• Respiratory infections and pneumonia — These can be caused by exposure to bacteria or viruses that cause respiratory infections in any age dogs and can be assessed with an oral or nasal PCR test. A chest X-ray will look for conditions such as bronchitis or pneumonia. Aspiration pneumonia can also develop from aspirated food or liquid, or inhaled foreign material. Symptoms include coughing, nasal discharge, and rapid or labored breathing that needs prompt treatment. It is treatable with antibiotics and herbal therapy, although severe cases may need supplemental oxygen and IV medication.
• Lung tumors or metastatic cancer — More common in older dogs. Tumors in the chest cavity, whether primary or spread from elsewhere, can impair breathing as they grow. They can cause a cough, exercise intolerance, or breathing difficulty.
• Pleural effusion — Fluid accumulates around the lungs rather than inside them, compressing the space available for breathing. Most cases stem from underlying heart disease, but this may also be caused by a mass on the heart or in the chest. Dogs with pleural effusion are often reluctant to lie down and more comfortable sitting or standing.
• Chronic bronchitis and pulmonary fibrosis — Chronic bronchitis causes persistent airway inflammation and mucus production — it may be due to underlying allergies or inflammation. Pulmonary fibrosis — which can result from previous heartworm infection damage or may be hereditary in certain breeds (West Highland White Terriers) causes scarring of lung tissue that limits oxygen exchange. Both lead to gradual-onset increased breathing effort and persistent cough.
• Pain — An often-overlooked driver. Arthritis flares, abdominal discomfort, post-surgical recovery, or any significant pain can increase breathing rate and panting through the body's stress response. Watch for restlessness, difficulty finding a comfortable position, or sensitivity to touch alongside the breathing change.
• Anemia — Reduced red blood cells mean reduced oxygen delivery, so the body compensates by breathing faster. Pale or whitish gums (instead of healthy pink) are a key indicator. It may be due to an underlying autoimmune disease, internal bleeding, or chronic kidney disease. A blood test is required for diagnosis.
• Cognitive dysfunction and anxiety — Senior dogs with cognitive decline may feel confused and frightened — particularly at night — leading to panting, pacing, and faster breathing when the house is quiet and environmental cues are limited.
• Cushing's disease and other hormonal conditions — Cushing's (overproduction of cortisol) is one of the more common endocrine disorders in middle-aged and senior dogs. It can cause persistent panting alongside a pot-bellied appearance, increased appetite, thirst, and urination, and in severe cases hair loss or skin changes. Thyroid issues and diabetes can also change breathing patterns.
• Medication side effects — Corticosteroids are a common culprit for new-onset panting. If breathing changes started after a new prescription, mention it to your vet.

The Red Flags That Can't Wait

Some signs mean you need to get to a vet immediately. If you see any of the following, skip the waiting-to-see-what-happens step and head to an emergency clinic or call your vet for immediate guidance:^7,8

• Blue, purple, gray, or white-tinged gums (severe oxygen deprivation).
• Open-mouth breathing while at rest — dogs are obligate nasal breathers at rest, so this is a serious signal.
• Breathing more than forty times per minute at rest that doesn't slow after calm rest in a cool environment.
• Extended neck posture, flared nostrils, elbows pushed out from the body, or “abdominal breathing” — visible movement of the whole chest and abdomen with each breath.
• Sudden onset in a dog who was previously breathing normally, especially with collapse or extreme weakness.
• Coughing up pink frothy fluid or any blood.
• Reluctance or inability to lie down comfortably.
• Any sign that your dog is struggling to get air.

For less dramatic changes — a mild increase in resting rate in a dog who's still alert and comfortable — a vet appointment within 24 to 48 hours is appropriate. Persistent fast breathing at rest that doesn't resolve over an hour warrants a same-day call.

What a Vet Will Do

A thorough evaluation usually includes listening to the heart and lungs with a stethoscope, chest X-rays to assess the trachea, lung fields, and heart size, and look for any fluid buildup or masses, bloodwork which may include a cardiac blood test (pro BNP), pulse ox to measure the blood oxygen level, blood pressure measurement, and sometimes an ECG (electrocardiogram) or echocardiogram (an ultrasound of the heart) to look for an arrhythmia as well as to assess the heart's structure and function.⁹

Treatment is directed at the underlying cause, so testing is necessary to find a diagnosis. Heart disease is managed with medications that reduce fluid buildup and support cardiac function. Respiratory infections get antimicrobials, herbal therapy, and supportive care. Laryngeal paralysis may be addressed with acupuncture or surgically. Tracheal collapse is managed with herbal therapy, cartilage support, medication, and lifestyle changes. The earlier any of these are diagnosed, the more options you have.¹⁰

Supporting Your Senior Dog at Home

Even outside of acute episodes, there's a lot you can do to make breathing easier for an aging dog:

• Keep home comfortably cool, especially in warmer months — heat adds significant respiratory load.
• Choose a harness over a collar to avoid pressure on the trachea, especially for small breeds prone to tracheal collapse.
• Keep sleeping areas quiet, well-ventilated, and free from disturbance.
• Avoid strenuous exercise and limit outings during warm or humid weather.
• Maintaining a healthy weight — excess weight makes every breath harder.
• Monitor resting breathing rate once a week while your dog is calm and asleep.
• Check gum color periodically — pink and moist is normal; pale, blue, or very dry is a warning sign.
• Reduce environmental triggers — scented candles, air fresheners, plug ins, smoke, and dusty rooms can all irritate aging airways.

A Season to Slow Down and Listen

Senior Pet Care Awareness Month is a gentle nudge to slow down and really look at the older dog in your life. Count breaths during their evening nap. Watch how they move after a walk. Listen to sounds that didn't used to be there. Notice if they're reluctant to lie flat or on their back the way they used to. These small observations, caught early, are what separate conditions that can be managed well from ones that reach crisis before anyone realizes what's happening.

Your old friend has slowed down with you over the years. If they're trying to catch their breath, they're telling you something — and the sooner you listen, the more you can do about it. Call your vet and schedule a chest X-ray and blood test. Describe what you've seen or share a video. Bring your breath-count log. For many of the conditions that cause breathing changes in senior dogs, early action is what buys more good years together on the couch, more quiet walks, and more mornings where they meet you at the door with that familiar tail wag you've loved for a decade or more.
