What this page is for
This describes what geriatric care for pets looks like and how it is organised. It prescribes nothing. Every symptom mentioned below has several possible causes, some trivial and some serious, and telling them apart requires examination and often bloodwork. The value of knowing the list is that it turns vague worry into a specific question you can put to a veterinarian.
When an animal becomes senior
There is no single birthday. Size drives it hard in dogs: giant breeds age into the senior bracket years before small ones, and a lifespan difference of half a decade or more between a great dane and a terrier is normal. Cats vary far less by size, and are commonly treated as senior somewhere around the low double digits, with a further geriatric bracket after that. Individual health, breed predispositions and body condition all shift the line.
The label matters mainly because it changes what the vet looks for. A cough in a young dog and a cough in a twelve-year-old are the same complaint with different differential lists behind them. If you want a rough placement, the dog age calculator accounts for breed size instead of multiplying by seven, and the cat age calculator does the equivalent for cats.
What actually changes
| Area | What you may see | Why it is worth raising |
|---|---|---|
| Mobility | Hesitation before jumping, slipping on hard floors, difficulty with stairs, stiffness after rest, a cat no longer reaching high perches | Osteoarthritis is common, under-diagnosed, and treatable. Cats in particular show it as reduced activity rather than limping |
| Cognition | Staring at walls, getting stuck behind furniture, disturbed sleep, night vocalising, confusion in familiar rooms, altered greetings | Cognitive dysfunction exists in both species and is managed better when raised early — but the same signs occur in pain, sensory loss and metabolic disease |
| Teeth and mouth | Bad breath, dropping food, chewing one side, tartar, drooling, reluctance with hard food | Dental disease is painful, extremely common, and animals rarely stop eating because of it, so owners routinely miss it entirely |
| Weight and appetite | Loss without a diet change, or gain as activity falls; increased appetite with weight loss | Unplanned change in either direction is a reason to book, not a reason to change food |
| Drinking and urination | More water, more or larger urinations, accidents in a previously reliable animal | Among the most useful early signals owners can supply, and one of the easiest to measure at home |
| Sight and hearing | Startling when approached, bumping furniture in dim light, ignoring calls, cloudy eyes | Sensory loss is manageable with environment changes, but the cloudy eye is also a thing a vet needs to look at |
| Lumps and skin | New masses, ones that change size, coat quality declining, overgrown nails | New or changing masses are examined rather than watched indefinitely. Less grooming in a cat can indicate pain |
| Behaviour | Irritability, hiding, reluctance to be handled, new avoidance of one household member | Chronic pain and cognitive change both surface as personality change first |
The single most useful reframe for owners of older animals: he is just getting old is a conclusion, not an observation, and it is one that a veterinarian should reach rather than you. Pain, dental disease, thyroid problems, kidney disease and cognitive dysfunction all masquerade as ordinary ageing, and several of them respond well to being caught.
Check-ups get more frequent, and more detailed
Older animals are typically seen more often than annually, because a year covers far more physiological change late in life than it does in the middle. Your vet sets the interval based on the individual. Senior visits also usually go beyond a physical exam — bloodwork, urinalysis, blood pressure and weight tracking build a baseline, and a trend across visits is worth more than any single result. Ask for your numbers, keep them, and bring the previous set.
Bring observations too, written down. Water bowl refills per day, stairs avoided, hours of sleep, nights of restlessness, food left behind, litter box changes. Owners are the only source of that data and memory reconstructs it badly under questioning. A short note on your phone updated weekly is worth more to the appointment than anything you will remember on the spot.
Changing the house instead of the animal
Most of what helps an ageing animal is environmental and costs little.
| Change | What it addresses |
|---|---|
| Runners, rugs or yoga mats over hard floors; keeping paw fur and nails trimmed | Slipping is the main reason weak-hindquartered dogs lose confidence and then lose muscle |
| Ramps or steps to bed and couch; a step into the car | Reduces jumping impact and keeps the animal in the family space rather than isolated on the floor |
| Litter box with a low entry, more boxes, one on every floor | Most senior cat house-soiling is an access problem, not a training problem |
| Water and food within easy reach, raised if neck extension is uncomfortable | Older animals drink less when it is inconvenient, which matters with kidney disease |
| Night lights along the route to water and the box | Failing sight plus night-time disorientation |
| Orthopaedic bedding away from draughts and traffic | Joint comfort and undisturbed sleep, which affects cognition |
| Shorter, more frequent walks; gentle play kept up | Maintains muscle without the flare that follows a weekend overexertion |
Diet, supplements and pain medication are all veterinary territory. Human anti-inflammatories are dangerous to both species, over-the-counter joint supplements vary enormously in quality and evidence, and prescription diets exist because they are matched to a diagnosis. Ask before adding anything, including things sold as natural.
Quality of life, and the last decision
At some point the conversation stops being about extending time and becomes about the quality of the time there is. That conversation belongs to you, your family and your veterinarian, and it goes better when it starts before the crisis rather than in an emergency room at midnight.
Vets often suggest a structured approach rather than a single judgment call: agree in advance on a handful of things that matter for this specific animal — eating willingly, moving without obvious pain, continence, interest in the household, more good days than bad — and mark them on a calendar daily. A record removes the two failure modes of doing it by feel, which are holding on through a long decline because each day resembles the last, and deciding on one catastrophic afternoon that was not representative. Ask your vet what they use; most have a version.
Practical matters are easier settled early: whether your clinic offers at-home euthanasia, whether there is a mobile service locally, what aftercare options exist and what they cost, and who in the family wants to be present. Making those calls while the animal is still comfortable is not morbid, it is the last piece of care you get to plan properly.
What nobody warns you about is how much of senior care is administrative — appointments, medications on a schedule, laundry, adjusting the house again. It is also the stretch where a fifteen-year relationship consists largely of small acts nobody witnesses. That is not consolation, exactly. It is just what the work looks like from inside it.
Questions people ask
How often should an older dog or cat be seen?
More often than annually, with the interval set by your veterinarian for that animal. The reasoning is that a year contains much more change late in life than in the middle, and early kidney, thyroid, dental and joint problems are far easier to manage when they are caught on a trend rather than at a crisis. Ask at the next visit what interval they want and why, and keep copies of the bloodwork so the trend is visible.
My old cat has started yowling at night. Is that just age?
Possibly, but it is a poor thing to assume. Night vocalising in an older cat is associated with cognitive dysfunction, and also with hyperthyroidism, high blood pressure, pain, hearing loss and other conditions, several of which are treatable. It is a specific enough complaint to be worth a visit. Note when it happens, how long it lasts and whether anything settles her, and take that with you.
What can I do at home for a dog with stiff joints?
Medication and diagnosis are veterinary work; the home side is about reducing load. Traction over slippery floors makes the largest difference, along with keeping nails and paw fur short. Ramps or steps replace jumping. Keep exercise regular and moderate rather than nothing all week and a long hike on Saturday, and keep weight down, since extra pounds are the heaviest single load on an arthritic joint. Do not give human anti-inflammatories under any circumstances.
How do people decide when it is time?
Rarely in a single moment, and rarely alone. Most vets will offer a quality-of-life framework — a short list of things that matter for that animal, scored day by day so you are reading a trend rather than one bad afternoon. Bring your record to the vet and ask them directly what they are seeing, including whether they think you are early or late. It is a decision made with a clinician and a family, and asking the question out loud does not commit you to anything.
Is dental cleaning worth the anaesthesia risk in an old animal?
That is a genuine risk-versus-benefit conversation to have with your vet rather than a default no. Untreated dental disease is painful and ongoing, and modern protocols use pre-anaesthetic bloodwork, individualised drugs and monitoring to manage risk in older patients. Non-anaesthetic scaling addresses appearance rather than disease below the gumline. Ask what the bloodwork shows, what the plan is, and what they would do with their own animal at this age.
