8 Signs of Canine Inflammaging Every Owner Should Know

In our first two posts, we covered what inflammaging actually is and where the research behind it comes from. This post is the practical one: what researchers have described as commonly-associated signs, so you know what you're actually looking for — not to create worry, but because recognizing a pattern is more useful than noticing eight separate, disconnected things.

One thing worth saying clearly before the list: none of these signs are unique to inflammaging, and none of them confirm anything on their own. They're the kinds of changes researchers and vets commonly associate with this process — but they can also just be normal variation, a completely different condition, or nothing at all. If you're noticing several of these in your own dog, that's a conversation for your vet, not something to self-diagnose from a blog post.

With that said, here's what to watch for.

1. Walks getting shorter, or tiring more quickly

Not a dramatic collapse — usually something subtler. The walk that used to be effortless now has your dog pulling toward home a little earlier, or panting more than they used to at the same distance.

2. Stiffness or hesitation getting up after resting

This is often one of the easiest signs to miss, because it's easy to file under “he's just stiff from napping” — which, to be fair, is sometimes exactly what it is. What's worth noticing is a pattern: the same hesitation, most days, especially after longer rest periods.

3. Less enthusiasm for play, toys, or activities

Dogs' personalities do shift with age, and not every dog stays a puppy at heart forever — that's normal and doesn't need an explanation. What's worth paying attention to is a genuine change from your own dog's baseline, not comparing them to how enthusiastic dogs are “supposed” to be.

4. Reluctance to jump, climb stairs, or get into the car

These are specific physical asks — extension, joint load, controlled landing — and they're often where subtle discomfort shows up first, before it's obvious in ordinary walking.

5. Takes longer to recover after exercise or activity

Less about how they perform during activity, more about how they seem for the rest of the day afterward. A dog who used to bounce back within the hour and now seems tired well into the evening is showing you something.

6. Sleeps more, or seems less comfortable and restless

Two signs that can look contradictory — sleeping more, or sleeping less comfortably — but both show up in discussions of age-related inflammation. Worth watching for either direction, not just one.

7. Digestive changes — gas, irregular stools, or food sensitivity

This one connects to something we mentioned in our first post: some researchers believe inflammaging affects gut health specifically, not just joints and mobility. A dog whose digestion has quietly become less predictable than it used to be may be showing a sign that has nothing to do with what they're eating that day.

8. Changes in movement — slower, less flexible, or favoring a leg

The broadest item on this list, deliberately — sometimes the sign isn't any one specific thing, just an overall sense that your dog moves differently than they used to. Trust that instinct. You know your dog's normal better than anyone.

Why owners often notice these but don't act on them

Here's something worth knowing: research looking specifically at this question found that owners frequently do notice these kinds of changes in their aging dogs — but a meaningful share of them don't bring it up with a vet, often because it gets filed under “just getting older” rather than something worth a conversation. Veterinary professionals surveyed in that same research overwhelmingly said they wished owners raised these signs sooner, not later.

That's really the point of this whole list. Not to diagnose anything yourself — just to close the gap between noticing something and acting on it.

If some of this sounds like your dog

That's worth a conversation with your vet, not a conclusion you reach on your own. If you want a starting point for organizing what you've noticed, we built a short checklist based on the signs researchers have described — you can walk through it here: Canine Inflammaging Checklist →
