Is it time? Signs to watch for in dogs
Dogs often keep trying to please us long past the point of comfort — which makes their decline easy to underestimate. Here's what vets look at in ageing and unwell dogs, and a checklist tuned to how dogs show (and hide) it.

The signs that carry the most weight
Mobility comes first for most dogs. Struggling to stand, slipping on floorboards, refusing stairs, or no longer managing the step out the back door — for a large dog especially, when their legs go, quality of life goes with them. Watch also for a dog who can no longer squat or lift a leg comfortably to toilet.
Breathing matters more than owners expect. Persistent panting at rest, especially at night, often signals pain or heart/lung trouble — dogs rarely pant at 2 am for no reason.
Withdrawal is the quiet one. The dog who no longer comes to the door, doesn't follow you room to room, turns away from patting they used to lean into. Dogs are social to their core; opting out of the family is a loud message delivered softly.
Appetite last — because many dogs eat keenly to the end. Refusing favourite foods is significant; still eating is not by itself reassurance.
Common conditions, common patterns
With arthritis, the question is whether pain relief still gives real relief — when a dog on full medication still can't rise without help, the medicine has done what it can. With kidney failure, appetite fading despite treatment and nausea that returns are the usual markers. With cancer, vets encourage owners to decide in advance what "enough" looks like — a first bad bleed, refusing food two days running — so the decision is made calm, not at midnight. With canine dementia, night pacing, getting stuck in corners and losing housetraining tend to progress; the question becomes how much of your dog's world still makes sense to them.
A gentle quality-of-life check
Tick anything that's true most days. Nothing is recorded — this is just for you.
Tick anything that sounds familiar — there are no right answers.
Large dogs: one practical note
For dogs too heavy to lift, decline is harder on everyone — and a clinic visit at the end can mean a stretcher, a car, and stress. This is the single most common reason families choose euthanasia at home for dogs: no final car ride, no lifting, their own bed.
Common questions
He still wags his tail. Surely that means he's okay?
A wag is love, not a health report. Dogs wag through pain to reassure us. Vets weigh the whole picture — mobility, breathing, appetite, engagement — not the tail.
Should we try one more treatment first?
Sometimes yes — ask the vet what a genuinely good outcome would look like and how likely it is. A fair question in return: is this buying good time for the dog, or buying time for us?
How fast do things change?
Slowly, then suddenly, is the honest answer for most conditions. Having a home-visit vet's number saved — before you need it — is a kindness to your future self.
When you want a professional eye
A home quality-of-life consultation lets a vet see your dog moving in their own space — often more revealing than a clinic exam. Ask a local vet to call you, with no obligation beyond the conversation.
