What to watch in senior dogs: touch sensitivity, crying and how they move

If you share your home with one of the senior dogs of the world, you may already watch them closely. A new owner survey suggests where to look. Dogs that flinched when touched or cried out for no clear reason were more often rated as having a poorer quality of life, and dogs that moved better were rated better.

The useful part is that you can see all of this yourself, with no equipment. It also seems to say more than a long list of diagnoses does.

How the study worked

Researchers collected anonymous online questionnaires from the owners of 789 dogs aged 8 or older. Owners described their dog’s chronic health conditions, behavior changes and mobility, and rated their dog’s quality of life, using parts of a standard canine quality-of-life framework. The results were published on Sept. 18, 2026, in Preventive Veterinary Medicine. Because it was a one-time survey based on what owners reported, it shows patterns that go together, not what causes what.

What they found

Older dogs often have several health problems at once, such as arthritis, dental disease or heart issues. You might expect the total number of conditions to decide how a dog is doing. In this survey, it did not stand out on its own once the researchers accounted for age and other factors.

What did stand out were things owners could see:

• Strong reaction to being touched. Dogs that reacted more to touch were more often rated as having a poorer quality of life. The study’s measure for this came out at 2.65.
• Crying or vocalizing with no obvious reason. No visitor, noise or other trigger, and the dog still cried out. This also went along with poorer ratings. The measure here was 2.04.
• Better mobility. Dogs that moved around more easily were less likely to be rated as having a poorer quality of life. The measure was 0.56, and a number below 1 means lower odds.

In plain words, how a dog acts and moves told owners more about how the dog was doing than how many diagnoses were on the chart.

Why would behavior say so much?

The researchers point out that changes like these can be signs of something that deserves a closer look. Flinching, crying out or moving stiffly can have several possible causes, and some of them can be managed. They help vets spot problems worth checking, and the study suggests this can round out the usual health history for older dogs.

That is a hopeful way to see it. A dog that cries out for no clear reason is not a lost cause. It is a dog telling you something you can pass along.

What you can do today

Take a few minutes this evening for a calm check-in with your dog. Run your hand gently over the back, hips and legs and watch the response. Does your dog pull away, flinch or yelp? Then watch how they get up, climb a step or start a walk. Jot down anything you notice, with the day, on your phone.

If something looks off, bring your notes to the next vet visit. Vets can often help with pain relief, physical therapy, weight control and small changes at home.
