Old Dog Panting Excessively (Should You Worry?)

It can be alarming to notice your senior dog panting excessively, especially if it’s happening even when they haven’t exercised or the weather isn’t hot.

While panting is a normal canine behavior, excessive panting in older dogs often signals something more serious than just heat or exertion.

We outline the common causes of an old dog panting excessively, what you can do at home, and when to seek veterinary help.

Old Dog Panting Excessively — Why It Happens

Excessive panting in senior dogs can stem from medical conditions, chronic pain, medication side effects, or anxiety.

Heart disease, heatstroke, respiratory disorders, and hormonal imbalances are frequent culprits. In some cases, dogs may pant more due to arthritis pain, cognitive dysfunction, or even tumors affecting their breathing. Because older dogs are more vulnerable to illness and stress, persistent panting is often a sign that something deeper is going on.

Common Causes of Old Dog Panting Excessively

Heart Disease

Heart disease is a common reason older dogs pant more than usual.

As the heart weakens, it struggles to pump blood efficiently, leading to poor oxygenation of the body. Dogs may compensate by breathing faster or harder, resulting in chronic panting.

Owners might also notice coughing, fatigue, or reluctance to exercise.

This condition is especially serious in senior dogs, as their bodies are less able to handle oxygen deficits or fluid buildup around the lungs.

Heatstroke

Older dogs are more prone to overheating, even in moderate temperatures.

Panting is a natural cooling mechanism, but if it becomes intense and unrelenting, it may point to heatstroke.

This is especially concerning for dogs with thick coats, short snouts, or pre-existing health conditions.

Signs include drooling, vomiting, red gums, and disorientation. Left untreated, heatstroke can cause organ failure and death.

Respiratory Conditions

Chronic bronchitis, collapsing trachea, and laryngeal paralysis are just a few respiratory conditions that cause excessive panting in older dogs.

These issues restrict airflow, making it harder for your dog to breathe normally.

You might notice wheezing, noisy breathing, or your dog stretching their neck while panting.

For seniors, these symptoms should be taken seriously as they can escalate quickly and may require lifelong management.

Pain or Discomfort

Pain is often overlooked as a cause of panting, but it’s a major contributor, especially in aging dogs.

Arthritis, dental disease, or even abdominal pain can trigger stress and cause your dog to pant excessively.

You may see subtle signs like limping, a hunched back, or avoiding stairs.

Because dogs hide pain instinctively, panting might be one of the few visible symptoms owners notice.

Cushing’s Disease

Cushing’s disease (hyperadrenocorticism) is common in older dogs and often leads to increased panting.

This condition causes the body to produce too much cortisol, a stress hormone that affects metabolism and fluid balance.

In addition to panting, you might see symptoms like increased thirst and urination, hair loss, or a pot-bellied appearance.

It’s a chronic illness but manageable with proper treatment.

Anxiety or Cognitive Dysfunction

Senior dogs may become more anxious or develop cognitive dysfunction syndrome (similar to dementia).

Changes in routine, vision loss, or confusion can cause them to pant due to stress.

They might also pace, whine, or seem disoriented.

While not immediately life-threatening, anxiety-related panting should still be addressed to improve your dog’s quality of life.

What to Do If Your Dog Is Old Dog Panting Excessively

Start by observing when and how often the panting occurs. Take note of the time of day, temperature, activity levels, and any changes in behavior or appetite.

Make sure your dog is in a cool, calm environment with access to fresh water. Reduce any stressors such as loud noises, unfamiliar guests, or disrupted routines.

If your dog seems overheated, offer cool (not cold) water and place them in a shaded or air-conditioned space. You can use a fan to promote air circulation.

For dogs with arthritis or known pain issues, avoid strenuous exercise and ask your vet about pain management options.

Try to keep a symptom journal. Documenting your dog’s panting episodes will help your vet make a more accurate diagnosis.

When to Call or Visit Your Vet

Call your vet immediately if your senior dog is panting excessively and shows signs of distress such as:

  • Blue or pale gums

  • Difficulty breathing or noisy respiration

  • Weakness or collapse

  • Persistent coughing

  • Vomiting or diarrhea

Also, seek veterinary help if the panting is sudden, worsens over time, or is accompanied by other unusual behaviors like confusion, pacing, or excessive thirst.

Excessive panting that doesn’t improve with rest or a change in environment should never be ignored in older dogs.

Early intervention can make a significant difference in both treatment success and your dog’s comfort.

Key Takeaway

Panting is normal, but excessive panting in older dogs should never be dismissed as just a sign of aging.

It can indicate serious underlying issues such as heart disease, respiratory problems, pain, or hormonal imbalances.

If you notice your old dog panting excessively, take proactive steps to keep them comfortable and monitor their symptoms closely.

Don’t hesitate to contact your vet, especially if the panting is accompanied by other concerning signs.

Your attentiveness can go a long way in ensuring your senior dog stays healthy, comfortable, and happy in their golden years.
