How to tell if your dog is getting old? 8 signs to watch out for

Comment savoir si mon chien vieillit ? 8 signes à surveiller

Has your dog passed the age of 7 and you feel like he's changing? This is normal: canine aging is a gradual process that affects all aspects of your companion's life. Knowing how to recognize the signs of aging will allow you to act early and significantly improve his quality of life.

At what age is a dog considered senior?

The age at which a dog becomes "senior" depends on its size:

  • Small breeds (under 10 kg): senior from 10-11 years old
  • Medium breeds (10-25 kg): senior from 8-9 years old
  • Large breeds (25-45 kg): senior from 6-7 years old
  • Giant breeds (over 45 kg): senior from 5-6 years old

Large breeds age faster because their metabolism is more stressed.

The 8 signs of aging to watch for

1. Difficulty getting up or lying down

If your dog hesitates before getting up, whimpers when changing position, or avoids lying on certain surfaces, it is often the first sign of joint discomfort. This sign should not be ignored: the earlier you act, the more you can slow the progression of osteoarthritis.

2. Reluctance to climb stairs or jump

A dog that used to refuse to get off the sofa and now hesitates to get on it is sending a clear signal: his joints are hurting. This behavior is very common in arthritic dogs.

3. General slowing down and less enthusiasm

Is your dog less eager during walks, stopping more often, or seeming less enthusiastic about going out? This slowdown is normal with age, but it can also signal underlying chronic pain.

4. Changes in sleep

A senior dog sleeps longer (up to 18 hours a day) but his sleep may be less restorative if he is in pain. He may get up several times during the night, change position frequently, or whimper in his sleep.

5. Unexplained weight gain or loss

Metabolism changes with age. Some dogs gain weight (which worsens joint problems), others lose it. Regular weight monitoring is important.

6. Cognitive changes

Like humans, dogs can develop a form of canine senile dementia (cognitive dysfunction syndrome). Signs: disorientation, forgetting habits, nocturnal barking without reason, staring into space.

7. Dull coat and appearance of white hairs

The coat loses its shine with age, and white hairs often appear around the muzzle and eyes. This is a visible but harmless sign of aging.

8. Increased sensitivity to cold or heat

Senior dogs regulate their body temperature less effectively. They may seek warmth in winter or suffer more from heat in summer, which worsens joint inflammation.

How to support your senior dog daily?

The good news: many of these signs can be alleviated with the right care. Here are the two essential pillars:

These two combined solutions make it possible to act on both the cause (joint inflammation) and the daily comfort of your senior dog.
