Senior Dog Coughing and Gagging: What Should I Do?

by | May 21, 2025 | Dogs, Health & Wellness

As our dogs grow older, their health needs shift in ways that can sometimes catch us by surprise. One issue that tends to raise concern is persistent coughing and gagging, especially when nothing seems to come up. While this can be distressing to witness, understanding what might be behind your older dog’s symptoms can help you respond with care and confidence.

Coughing in senior dogs can stem from several different causes, including respiratory infections, allergies, heart conditions, and even structural changes in the throat or windpipe that occur naturally with age. As dogs get older, their respiratory systems become more sensitive, making them more prone to irritation and illness.

Environmental factors, such as dust, smoke, or strong cleaning products, can also trigger coughing fits in senior dogs.. Identifying and minimizing these irritants can make a meaningful difference in your dog’s daily comfort.

Common Health Conditions That May Be Causing the Cough

Dogs can develop chronic health issues as they age, which may lead to frequent coughing or gagging. Here are a few possibilities to be aware of:

  • Chronic Bronchitis: This is an inflammatory condition that affects the airways. It tends to produce a dry, hacking cough that can worsen over time if not addressed.
  • Heart Disease: Conditions like congestive heart failure may cause fluid buildup in the lungs, leading to frequent coughing, especially at night or after activity.
  • Collapsed Trachea: This is more common in small breeds and produces a distinctive honking sound. It occurs when the windpipe weakens and flattens, making it harder for air to pass through.

When Should You Be Concerned About Your Dog’s Cough?

It’s not unusual for dogs to cough occasionally, especially after drinking water too quickly or playing. But if the cough becomes frequent, or if you notice any of the following signs, it may be time to check in with your vet:

  • Coughing that lasts longer than a week
  • Gagging or trying to bring something up with no success
  • Unusual breathing patterns, like wheezing, rapid breathing, or labored breathing
  • Loss of appetite, weight loss, or visible lethargy

What You Can Do at Home to Help Your Dog Feel Better

While a vet visit is always the most important step for diagnosing ongoing coughing, there are some ways you can offer comfort and support to your dog at home in the meantime:

  • Create a Calm, Clean Space: Make sure your home is free from strong odors, cigarette smoke, and airborne dust. A peaceful environment can do wonders for your dog’s breathing.
  • Keep Them Hydrated: Water helps soothe the throat and supports the immune system. You might even consider offering warm broth as a comforting option.
  • Try a Humidifier: Dry air, especially during winter months, can irritate your dog’s airways. A humidifier can add gentle moisture to the air and ease coughing spells.

When It’s Time to Call the Vet

Some coughing episodes can wait a day or two to monitor,, but if your dog’s condition doesn’t improve or seems to worsen, it’s best to consult a veterinarian. Here’s when to make that call:

  • The cough is frequent or severe
  • There’s mucus, blood, or gagging involved
    Your dog seems tired, withdrawn, or not interested in food
  • Home care hasn’t helped within a few days

How Vets Diagnose Coughing in Older Dogs

When you visit the vet, they’ll likely begin with a thorough physical exam, including listening to your dog’s heart and lungs. Depending on what they hear or suspect, they might suggest:

  • X-rays or imaging to examine the lungs, trachea, or heart
  • Blood work to check for infection or inflammation
  • Additional tests, such as a tracheal wash or bronchoscopy, may be necessary

Treatment Options for a Coughing Senior Dog

Treatment will depend entirely on the diagnosis, but here is what  Sandra C. Mitchell, DVM, DABVP said in the PetMD article:

“Most cases of dog gagging are relatively straightforward to treat. Even the causes that are more significant—such as from pneumonia or laryngeal paralysis—have treatments available to either cure or significantly reduce the gagging and make your dog more comfortable.

Once a diagnosis is made, your veterinarian may recommend specific treatments to address the underlying reason for the cough (such as antibiotics for an infection), or medications designed to reduce the severity of the cough. 

In some cases, it may be necessary to consider lifestyle changes such as elevating food and water bowls to minimize the effect of laryngeal paralysis. You may even consider changing your pup’s collar and leash to a harness to reduce the effects of a collapsing trachea.”

How to Help Prevent Respiratory Issues in Older Dogs

While not all coughing can be prevented, there are a few steps you can take to keep your senior dog’s respiratory health in better shape:

  • Stay on top of routine vet visits—early detection matters.
  • Keep vaccinations current, especially for illnesses like kennel cough.
  • Maintain a healthy weight and balanced diet, as obesity can put extra strain on the lungs and heart.
  • Avoid exposure to smoke and harsh chemicals, which can irritate sensitive airways. 

Watching your senior dog struggle with coughing or gagging can be worrisome, but by being attentive to changes in their behavior and seeking veterinary guidance when needed, you’re doing the very best for your furry family member.

Your dog may be aging, but your care, patience, and love continue to make all the difference. With the right support, many older dogs can live comfortable, happy lives—even with chronic conditions. If you’re ever in doubt, don’t hesitate to reach out to your vet. A simple check-up can offer peace of mind and help your dog breathe easier.
