When an older dog starts panting excessively and becomes unusually clingy, it can leave any dog owner feeling uneasy.
Panting in dogs is normal after exercise or in warm weather, but when it becomes constant—especially alongside clingy or anxious behavior—it often signals something deeper.
We outline the common causes of excessive panting and clinginess in old dogs, what you can do at home, and when to seek veterinary help.

Old Dog Panting Excessively and Clingy — Why It Happens
An old dog that’s panting excessively and acting clingy may be struggling with anxiety, pain, heat stress, or underlying illness. Aging affects how a dog’s body regulates temperature, handles stress, and processes hormones.
Many senior dogs pant more due to joint pain, heart problems, or breathing issues, while emotional changes—like confusion or separation anxiety—can make them stick close to their owner.
Sometimes the cause is environmental (like heat or medication side effects), but other times it’s a sign of an age-related condition that deserves attention.
Old Dog Panting Excessively and Clingy: Common Causes
1. Pain or Discomfort
Pain is one of the most common triggers of panting in older dogs. Arthritis, joint inflammation, dental pain, or internal discomfort can cause persistent panting as the body’s natural stress response. Pain also makes dogs seek reassurance—hence the clinginess.
If your senior dog pants heavily even while resting, shifts around often, or seems restless at night, discomfort could be the culprit.
They may also lick or chew sore areas or struggle to lie down comfortably. Pain relief prescribed by your vet can bring both their breathing and anxiety back to normal.

2. Anxiety and Cognitive Decline
As dogs age, they can develop canine cognitive dysfunction (similar to dementia in humans).
This can lead to confusion, restlessness, and new behavioral changes like following their owner everywhere or whining when left alone. Panting is a common physical sign of stress in these moments.
You might notice your senior dog pacing at night, staring blankly, or becoming anxious when routines change.
Keeping a predictable schedule, providing mental enrichment, and ensuring a calm environment can help reduce this anxiety-driven panting.
3. Heat Stress or Overheating
Older dogs are more sensitive to temperature changes. Their ability to regulate body heat declines, making them prone to overheating even in mild warmth.
Excessive panting is the body’s main cooling mechanism, and clinginess may indicate distress or confusion caused by heat exhaustion.
If your old dog is panting heavily indoors or after minimal activity, check for signs like bright red gums, drooling, or wobbliness.
Move them to a cool, shaded area, offer water, and monitor closely. Severe overheating can escalate to heatstroke—an emergency requiring immediate veterinary care.
4. Heart Disease
Heart conditions are common in senior dogs and often cause both panting and restlessness.
When the heart struggles to pump efficiently, fluid can build up in the lungs, making breathing harder. The dog may pant to compensate for low oxygen levels and may also become clingy because they feel unwell.
Other signs include coughing (especially at night), fatigue, and reluctance to exercise. If your dog’s breathing appears shallow or labored, schedule a veterinary exam and chest x-rays. Early treatment—such as medication to reduce fluid buildup—can greatly improve comfort and longevity.
5. Hormonal Imbalances (Cushing’s Disease)
Cushing’s disease, caused by overproduction of cortisol, frequently affects older dogs and leads to chronic panting, thirst, and behavioral changes.
Dogs with Cushing’s often pant excessively even when relaxed, and they may act clingy or restless due to hormonal stress and fatigue.
Look for other signs like increased urination, thinning coat, or a pot-bellied appearance. Diagnosis involves blood tests, and treatment can significantly reduce symptoms once cortisol levels are controlled.
6. Medication Side Effects
Certain medications, especially steroids like prednisone, can increase panting and restlessness in senior dogs.
These drugs alter hormone balance and can temporarily make dogs feel jittery or uncomfortable, leading to clingy behavior.
If your dog started panting excessively after beginning a new medication, contact your vet. They may adjust the dosage or switch to an alternative that’s easier on your dog’s system.

What to Do If Your Old Dog Is Panting Excessively and Clingy
When your old dog starts panting heavily and shadowing you around, start by observing their surroundings and behavior.
Check the temperature—make sure the room isn’t too warm and provide a cool, comfortable resting spot. Offer fresh water and avoid outdoor activity during hot hours.
Watch for signs of distress like trembling, pacing, or restlessness at night. Gentle reassurance and calm routines help reduce anxiety. Keep noise levels low, and ensure your dog has a quiet, safe space where they can relax without feeling isolated.
If your dog’s panting seems linked to stress or separation, try leaving familiar items nearby, such as your scent or their favorite blanket. Short calming walks or gentle massages can also help soothe their nerves.
However, if panting continues when your dog is relaxed, or if they’re also coughing, vomiting, or showing weakness, a vet visit is necessary. Bring notes about when the panting occurs (day vs. night, activity level, recent changes) to help your vet pinpoint the cause more quickly.
When to Call or Visit Your Vet
You should contact your vet if your old dog’s excessive panting and clinginess last more than a day or two, or if other symptoms appear.
Panting that occurs even at rest, worsens at night, or is accompanied by coughing, lethargy, or loss of appetite can indicate heart or lung problems.
Seek emergency care if your dog:
Pants excessively with a wide-open mouth and glazed eyes
Collapses or can’t stand
Has blue or pale gums
Vomits repeatedly or can’t cool down
These could signal heatstroke, respiratory distress, or organ failure. Early diagnosis is key, especially for older dogs with fragile health. Your vet may recommend bloodwork, x-rays, or an ECG to identify heart or hormonal causes.
Even if symptoms seem mild, frequent panting and clingy behavior shouldn’t be ignored. These changes often reflect discomfort or fear that your dog can’t express in other ways.

Key Takeaway
Panting and clinginess in older dogs can be emotional or physical—or a mix of both.
While some cases stem from mild anxiety or age-related confusion, others may point to pain, heart disease, or hormonal imbalance.
The best approach is to stay observant and responsive. Keep your dog comfortable, maintain a calm environment, and monitor changes closely. If panting persists or your dog seems distressed, contact your vet promptly.
Your senior dog relies on you to interpret these signs of discomfort. With early care and attention, you can help them stay calm, comfortable, and by your side for many more loving years.
