Hearing an old dog making grunting noises can be puzzling and sometimes concerning. While it may sound harmless or even a little funny, grunting in senior dogs can be a sign of discomfort or underlying health issues.
We outline the common causes of grunting noises in old dogs, what you can do at home, and when to seek veterinary help.
Old Dog Making Grunting Noises — Why It Happens
Grunting in older dogs can be linked to several factors, ranging from natural aging changes to more serious health concerns. Some dogs grunt when lying down due to pressure on their chest or lungs, while others may grunt because of obesity, arthritis pain, respiratory conditions, or heart problems.
In many cases, grunting is your dog’s way of communicating discomfort or adjusting to age-related changes in their body. But persistent or unusual noises should never be ignored, especially in senior dogs.
Old Dog Making Grunting Noises: Common Causes
Relaxation or Contentment
Sometimes, grunting is simply a sign that your old dog is relaxed.
Many dogs make a soft grunt when they settle into their bed, stretch out, or enjoy being petted. This noise is usually harmless and comparable to a human sigh of contentment.
If your dog is otherwise healthy, eating well, and showing no signs of distress, grunting in these situations is not a cause for concern.

Obesity and Pressure on the Chest
As dogs age, they may gain extra weight that puts added pressure on their lungs and chest.
This can cause a grunting sound, especially when lying down or resting on their side. The extra fat makes breathing slightly more labored, leading to these low noises.
Weight-related grunting should be taken seriously since obesity in old dogs can contribute to heart disease, arthritis, and decreased quality of life.
Arthritis or Joint Pain
Arthritis is extremely common in senior dogs and can cause discomfort when moving, lying down, or getting up.
Some old dogs grunt when shifting positions or lowering themselves to the ground because the movement causes brief pain or stiffness.
If you notice your dog grunting while changing posture, along with limping or slower movement, arthritis could be the cause.
Respiratory Issues
Conditions such as bronchitis, collapsing trachea, or chronic respiratory infections can cause grunting or labored breathing sounds.
The grunting may be more noticeable at night or after exercise, and you may also hear wheezing or coughing.
Because old dogs are more prone to respiratory illnesses, persistent grunting tied to breathing should not be ignored.
Heart Disease
Heart conditions, especially congestive heart failure, can cause fluid buildup in the lungs and chest cavity.
This fluid interferes with normal breathing, sometimes creating grunting or groaning noises. Other signs include coughing, reduced stamina, or restlessness at night.
Since heart disease is a common problem in senior dogs, grunting noises paired with these symptoms warrant immediate veterinary attention.

Gastrointestinal Discomfort
Older dogs sometimes grunt when experiencing bloating, gas, or digestive discomfort.
The pressure in the abdomen can make breathing slightly harder, leading to grunting sounds when lying down. You may also notice pacing, a tense belly, or loss of appetite.
While mild digestive upset can resolve on its own, bloating in particular can be life-threatening and requires urgent care.
What to Do If Your Old Dog Is Making Grunting Noises
If your old dog grunts occasionally while resting or enjoying affection, it may simply be a normal, harmless behavior. Observe when the noises happen and whether they’re associated with relaxation or potential discomfort.
Make your dog’s resting areas more comfortable with soft, supportive bedding. For arthritic dogs, orthopedic beds can reduce pressure on the joints and minimize discomfort-related grunting.
If weight seems to be a factor, speak with your veterinarian about safe weight-loss strategies for senior dogs. Even small amounts of weight reduction can ease pressure on the chest and improve breathing comfort.
Keep track of any additional symptoms such as coughing, lethargy, appetite changes, or restless sleep. These can help your vet determine whether the grunting is linked to a more serious underlying condition.
Most importantly, avoid assuming grunting is always harmless in older dogs. If it’s new, persistent, or worsening, schedule a veterinary exam.
When to Call or Visit Your Vet
You should contact your vet promptly if your old dog’s grunting is accompanied by labored breathing, coughing, or fainting spells. These are possible signs of heart or respiratory disease.
Seek care if your dog grunts frequently when lying down or shows signs of pain, restlessness, or difficulty moving. Arthritis or gastrointestinal discomfort may be involved, and these conditions require treatment.
Emergency care is needed if your dog has a swollen abdomen, cannot settle comfortably, or appears to be in distress while breathing. These may indicate life-threatening problems such as bloat or advanced heart failure.
When in doubt, it’s always better to have your old dog checked rather than risk missing a serious issue.

Key Takeaway
Grunting in old dogs can be perfectly normal in some situations, such as when settling down to rest, but it can also be a sign of pain, breathing problems, or heart disease.
Keep an eye on when the noises occur, how often they happen, and whether your dog shows any other signs of illness.
At-home comfort measures can help, but persistent or concerning grunting should always be discussed with your veterinarian.
With attentive care and timely veterinary guidance, you can help ensure your old dog stays as comfortable and healthy as possible in their senior years.
