Caring for a Senior Dog: Signs to Watch For and What Helps
A dog getting older sneaks up on you. It's rarely one big change, more a string of small ones that only add up when you look back. Here's what to actually watch for, and what genuinely helps once you spot it.
TL;DR — key points
- Early signs are subtle: slower to rise, hesitating at stairs, shorter walks, a greying muzzle
- Joint problems affect around 80% of dogs over 8, often mistaken for "just getting old"
- Cognitive decline (doggy dementia) is real, not curable, but manageable with a vet's help
- Twice-yearly vet checks are worth it once a dog's around 7 or older
- A sudden or rapid change is never "just age", get it checked
The early signs
Nothing dramatic at first, usually: slower to get up after a nap, a bit of hesitation before stairs or the car, walks that get shorter and slower without you really deciding that, more sleep than before, and a muzzle that's greyer than it used to be. On their own, none of these mean much. Together, or arriving quickly, they're worth paying attention to.
Joint pain and arthritis
This is far more common than most owners realise, affecting around 80% of dogs over eight years old. It's also the thing most often written off as "just getting old" when it's actually something a vet can genuinely help with. Watch for limping, walking slower than usual, avoiding stairs, or no longer jumping onto the sofa or into the car.
A vet visit comes first, since proper diagnosis shapes everything else. From there, what tends to help: keeping your dog at a healthy weight (extra weight means extra pressure on already sore joints), and swapping to shorter, more frequent walks over one long one.
Swimming is worth trying too, it's low-impact in a way normal walking isn't. My guide to how much walking a dog needs covers this in the "Older dogs" section, including a real example of it helping a regular of mine.
Joint supplements can help as well, omega-3, glucosamine and curcumin have the best evidence behind them, but it's worth asking your vet which product and dose actually suits your dog rather than guessing off a shelf.
Dogs just naturally slow down with age, there's nothing to be done about it.
Slowing down is often the first visible sign of joint pain, not just age on its own. A vet can tell the difference, and if it is arthritis, there's genuinely a lot that can be done to help.
Home comfort
Small changes make a real difference: a supportive, padded bed somewhere draught-free, a rug over slippery flooring so stiff legs don't slide, a ramp or step if the sofa or car has become a struggle, and making sure the garden or a toilet spot is easy to reach without a long walk to get there. Older dogs also feel the heat more, my guide to hot weather safety has more on keeping any dog cool, but a frozen treat on a warm day is always a favourite with my older regulars.
Cognitive changes (doggy dementia)
Cognitive dysfunction is real, and it's more common than people expect in older dogs. Signs include confusion or seeming lost in places they know well, house soiling out of nowhere, restlessness or pacing at night, staring at nothing in particular, changes in appetite, and new fears or irritability that weren't there before. There's no cure, but it can be managed, a vet can prescribe medication and help you adjust routines at home, and the earlier it's picked up, the better the outcome tends to be.
Appetite changes
A senior dog going off their food, or suddenly getting fussy, is common, but it's always worth ruling out a medical cause first rather than assuming it's just pickiness. My guide to picky eaters covers the difference between ordinary fussiness and something that needs a vet, and my guide to treats and human food is worth a look too, since keeping a senior dog at a healthy weight matters more than ever for their joints.
Six-monthly check-ups are the ideal, not an obligation. Vets generally recommend them once a dog's around seven or older, since they catch changes in weight, joints, teeth and general health earlier than an annual visit alone.
But with money tight for a lot of people right now, that's not always realistic, and there's no need to feel guilty if it isn't. Keeping a closer eye at home between visits, and mentioning anything that's changed at whatever check-up you can manage, still makes a real difference.
If cost is the barrier, PDSA offers free or low-cost treatment to owners on certain means-tested benefits (Universal Credit without the housing element, Housing Benefit or Council Tax Support), worth checking their eligibility tool if that could apply to you.
Curious roughly where your dog sits in human years? My dog age calculator gives an estimate based on size rather than the old x7 myth. And if you're further down this road and thinking about quality of life more seriously, my guide on making the most of a dog's final days covers that gently, when you're ready for it.
Where this advice comes from
I've written all of the above in my own words, but the medical facts aren't mine to make up. I've checked it against the vets who publish this properly, and their versions are worth reading in full:
- PDSA on caring for your senior dog's joints
- PDSA on dementia in dogs (cognitive dysfunction)
- Cornell University College of Veterinary Medicine on senior dog dementia
- PDSA on eligibility for free or low-cost treatment
