How to Help an Older Dog With Stiff Joints and Slower Movement
Share
Last reviewed: June 2026
Your dog used to take the stairs two at a time. Now there's a pause at the bottom, a little gather before the climb. They're slower to get up after a nap, slower to settle at night, and the morning walk has turned into more of a stroll. None of it happened overnight, which is exactly why it's easy to miss, until one day you notice your dog moving like an older dog.
Stiff joints and slowing movement are one of the most common parts of a dog getting older. The good part: a lot of what makes a stiff dog more comfortable is in your hands, and most of it is small, daily, and gentle. Here's what actually helps.
Start with a vet visit, not a supplement
This is the step people want to skip, so it goes first. "Slowing down" can be plain age, but it can also be arthritis, an old injury flaring up, or pain that has nothing to do with joints at all. You can't tell the difference by watching, and the right plan depends on the cause.
A vet can confirm what's going on and, if there's real pain, prescribe something for it. Anti-inflammatories (NSAIDs) are often the first tool for arthritis because they bring swelling and discomfort down quickly. Everything below works best alongside that, not instead of it.
Keep them lean
If your dog is carrying extra weight, this is the single biggest thing you can change. Every extra pound is more load on joints that already ache, and arthritis shows up more often in heavier dogs. You don't need a crash diet, just an honest look at portions, fewer table scraps, and measuring meals instead of eyeballing them. A leaner dog moves easier, full stop.
Keep them moving, gently
It's tempting to let a stiff dog rest all day, but stillness makes stiffness worse. Muscle keeps joints supported, and muscle fades fast when it isn't used. The aim is low-impact and regular: a couple of short, flat walks instead of one long one, sniff-walks where your dog sets the pace, and, if they like water, swimming, which lets them move without putting weight on sore joints.
Watch the line between "good tired" and "sore tomorrow." If a longer outing leaves your dog stiffer the next day, scale it back.
Make the house easier on them
Small changes around the home remove the moments that hurt most:
- Rugs or runners over slippery floors, so legs don't splay out on tile or hardwood.
- A ramp or a step up to the couch, the bed, or the car, so there's no jarring jump.
- An orthopedic bed that supports the joints instead of letting them press into the floor.
- Warmth. A stiff older dog is usually worse in the cold. A warm sleeping spot, and a warm compress on a sore hip after activity, can take the edge off.
Support the joints from the inside
This is where diet comes in, and where a fish oil like salmon oil earns its place.
Omega-3 fatty acids (specifically EPA and DHA, which oily fish are rich in) calm the kind of inflammation that drives joint pain. The research here is genuinely encouraging: in one double-blind veterinary trial, dogs given fish oil showed roughly a 50% improvement in pain and joint signs over six weeks, while the placebo group didn't budge (dvm360 / JAVMA). It isn't a cure, and the effect is strongest at a proper daily dose rather than a token splash on dinner, so it's worth asking your vet how much is right for your dog's weight.
Calmi Salmon Oil is pure, unrefined Norwegian salmon oil, a clean, single-ingredient source of those EPA and DHA omega-3s. You pump it over food once a day, and most dogs treat it like gravy. Next to the basics above, it's an easy daily habit that works on joint comfort from the inside while everything else works from the outside.
(One note: fish oil suits most dogs well, but too much too fast can cause loose stool. Start with a small amount and build up.)
Be patient, and change one thing at a time
You won't fix a stiff dog in a weekend, and you don't have to. Pick one or two of these to start (usually weight and a daily omega-3 are the easiest wins), give it a few weeks, and watch how your dog moves. Comfortable movement comes back in small steps: an easier climb up the stairs, a bit more spring on the morning walk, getting up without the groan.
Your older dog isn't asking to be young again. They're asking for the day to be a little easier. That part, you can do.
Always check with your veterinarian before starting a new supplement or changing your dog's exercise routine, especially if they're on medication.
