Old dogs: everything you need to know about your senior dog

Posted in : on 27-01-2026

As your dog ages, a lot changes – both physically and mentally. An old dog has different needs than a young dog, and as an owner, you naturally want the best for your faithful friend. But how do you actually know when a dog is old? What are typical signs of aging in dogs? And more importantly, how do you recognize when your dog has run out of steam or is perhaps even ready to be put to sleep?

In this blog, we explain everything you need to know about the old dog: from symptoms and behavior to nutrition, care and support.

 

When is a dog a senior?

On average, we call a dog “senior” starting at 7 years of age, but it depends on the breed and size. Small dogs tend to get older than large dogs, so an 8-year-old Chihuahua is still relatively young, while an 8-year-old Great Dane is already truly a senior.

Note changes such as:

  • Sleep more
  • Less playful behavior
  • Walking more slowly
  • Drinking and urinating more

 

Symptoms in an old dog

As your dog ages, you may notice certain physical and mental signs. Here are the most common symptoms and what they may mean:

Physical symptoms in your older dog

  • Panting a lot and being restless: this may indicate pain, heart problems or stress.
  • Pees in the house or drips urine: possibly incontinence, a well-known aging symptom.
  • Won’t eat or just keeps eating: changes in appetite may indicate dental or metabolic problems.
  • Trembling hind legs or limping: often indicates osteoarthritis or muscle weakness.
  • Drinks a lot and urinates a lot: watch for kidney problems or diabetes.
  • Stinky breath or rotten teeth: dental disease is common in older dogs.

 

Mental changes evident in older dogs

  • Behavior change in an old dog: more affectionate, restless, or just withdrawn behavior.
  • Loss of potty training: may indicate dementia or physical discomfort.
  • Restless nights, barking or running around: often a signal of old age, confusion or pain.

 

How do you know when your dog is really not doing it anymore?

It’s not an easy question, but one that sometimes comes with it as your dog ages. Try to pay particular attention to how he feels and whether he can still enjoy the things he likes to do.

Is your dog still eating and drinking?

Does he still enjoy walks?

Is there a lot of pain or discomfort?

Can he still move normally?

Is he often anxious, restless or withdrawn?

If you have to answer “no” multiple times, maybe it’s time to talk to your vet about putting your old dog to sleep. We understand how hard this is, take your time and trust your gut.

 

Common ailments of aging in dogs

An old dog may suffer from various ailments of old age:

Osteoarthritis: stiff movement, difficulty getting up
Kidney problems: lots of drinking, decreased appetite
Heart problems: lots of panting, tired quickly, fat belly
Dementia (CDS): disorientation, restlessness, squeaking at night
Epilepsy: seizures, shocks, fainting
Dental problems: bad breath, unwillingness to eat, bleeding or inflamed gums

 

What does an old dog need?

Like humans, older dogs need different care. Read more tips on how to keep your older dog fit here. Consider further:

  • Soft dog food or fresh food for senior dogs
  • Regular health checks
  • Supplements for joints, memory and resistance
  • A comfortable place to sleep
  • Quiet walks adapted to their pace

 

Supportive supplements for old dogs

For older dogs, it is especially important to properly support their bodies. As they age, joints can feel stiffer and exercise can be less natural. Our supplements are therefore specially formulated for (senior) dogs, with natural ingredients to suit their changing needs.

This is how Jointpower joints, ligaments and tendons, and carries Dental Care contributes to healthy teeth, strong gums and fresh breath. Want to give your dog complete support? Then choose the Senior Combi Deal: a powerful combination of Devil’s claw and Glucosamine MSM. These two products work together to keep the musculoskeletal system supple and prevent wear and tear of cartilage.

Finally, keep listening to your dog

An old dog is often even sweeter and more loyal than before. He deserves all the rest, love and care in the world. Pay close attention to changes, stay in touch with your veterinarian and get help in time.
