Adopting a senior dog: the first 72 hours checklist

Adopting a senior dog is one of the kindest bargains in the dog world: you get a dog whose character is already formed, usually past the chewing and chaos years, and the dog gets a home for the chapter that matters most. It is also special in one honest way. The dog's history may be thin. You may know little about past health, habits or fears, and the dog has just lost whatever home it knew. Patience and routine do the work here. A predictable day tells an old dog, faster than anything else can, that this place is safe and staying.

Print this checklist and work through it in order. It assumes a senior pace: calm arrivals, short walks, lots of sleep and a vet visit in the first week. Timings are a guide, not a test. A very old or frail dog may take each stage more slowly, and that is fine. Let the dog set the speed, keep notes on what you learn, and share them with your vet, because with a thin history your observations in these first days are genuinely useful medical information.

Before the dog comes home

Choose a vet and register the dog, or be ready to register on day one.
Ask the shelter for the medical records, and the current food and medication list.
Set up a quiet corner: a supportive bed, a non slip rug and a water bowl.
Add a ramp if there are steps the dog will need every day.
Keep the house calm and ready, with leads, bowls and cleaning basics to hand.

The first 24 hours

Arrive quietly, with no visitors queue waiting to meet the new dog.
Offer garden toilet trips on a lead, often, and praise every success.
Feed the same food as the shelter, in small calm meals.
Allow short, gentle exploration of one or two rooms, then rest.
Expect lots of sleep. A new home is tiring, and sleep is how dogs settle.

Days 2 to 3

Book the first vet visit within the first week, sooner if anything worries you.
Start the feeding and walk rhythm you mean to keep, at calm senior pace.
Learn the dog's toilet signals, which may be subtle or still forming.
Begin gentle handling checks at the dog's pace: ears, teeth, coat and paws.
Keep walks short and local while the dog maps the new neighbourhood.

The first week

Set the routine: meals, walks and rest at steady times each day.
Introduce household sounds and people gradually, one thing at a time.
Find out what the dog loves: sniffing, cuddles, a ball, a sunny spot.
Note appetite, water, sleep, toilet habits and any stiffness in a simple log.
Let the dog choose contact. Trust in week one is built by not rushing it.

The first month

Book the senior health check with bloodwork, if it has not been done yet.
Review weight, teeth and joints with the vet and agree a care rhythm.
Build the exercise rhythm slowly, a little more distance as the dog settles.
Start gentle brain games and short training refreshers, heavy on rewards.
Celebrate the small wins. A settled old dog blooming is a quiet joy.

After the first month, settle into the rhythm in our vet checks guide: twice yearly visits, a simple home log, and gentle daily life shaped by the guides in the senior dogs hub. If you are also raising a puppy one day, our sister checklist, the puppy first year checklist, covers the other end of life with the same honest approach. Different stage, same principle: show up, keep the routine, and enjoy the dog in front of you.
