5 Subtle Signs Your Dog Is Becoming a Senior
Apr 01, 2026
As dog owners, we wish our dogs could stay young forever. But unfortunately that's not the case.
Recognizing early changes is one of the most beneficial things you can do to support your dog’s comfort, mobility, and quality of life.
Here are 5 signs to look for:
1. Slowing Down on Walks or During Play
If your dog used to lead the walk and now lags behind—or loses interest in games they once loved—this can be one of the earliest signs of aging.
What to watch for: shorter bursts of activity, more frequent stopping, or hesitation on longer walks.
2. Difficulty with Lying Down, Sitting down or Using Stairs
Are you noticing they are taking longer to stand up, struggling after resting or Avoiding stairs or jumping?
What to watch for: stiffness after rest (especially in the morning or after naps).
3. Changes in Weight
Weight changes can happen in both directions as dogs age.
What to watch for: subtle body shape changes, especially along the back, hips, and ribs.
4. Increased Sleeping (Lower Energy Overall)
What to watch for: Less excitement for daily routines and / or sleeping through activities they used to enjoy.
5. Behavioral Changes / Irritability
As dogs age, they may become more anxious or clingy, show irritability when touched (especially if painful areas are involved, and seem less tolerant than usual.
What to watch for: personality shifts that feel “out of character”
When is my dog considered a senior?
There’s no exact age that applies to every dog but here are parameters to keep in mind:
- Small dogs: around 8–10 years
- Medium dogs: around 7–9 years
- Large dogs: around 6–8 years
But more important than age is what you’re seeing at home.
If you’re starting to notice these changes, you’re not alone—and you don’t have to figure it out on your own.
