Bringing home a rescue dog: the first weeks (UK)
Updated 6 October 2026 · 4 min read
A rescue dog may not have lived in a home for a while, and everything about yours is new. Here's how to help them settle, what to have ready, the microchip and tag to sort out, and how to keep them safe in the first weeks, when they don't yet know where home is, from Dogs Trust and Battersea's advice and the law.
Before they arrive
- A bed and blanket, food and water bowls, food, toys, and something to chew or lick.
- A quiet safe space, away from people, where your dog can take themselves off and be left alone. Battersea suggests making sure everyone in the house knows not to disturb them there.
- A collar, a lead and an ID tag with your name and address on it, which the law asks for in public.
- A secure garden: check for gaps under fences, and gates that don't close properly.
The first days
- Let them settle at their own pace. Dogs Trust points out that adult dogs may be worried when they arrive, so don't fuss them or force them to interact: let them come to you.
- Avoid having visitors for the first few days at least, as Battersea advises.
- Create a routine and stick to it, so they know what to expect, and introduce them carefully to any other pets.
- Keep walks short and in the same place, so they can get their bearings.
Sort out their ID straight away
Dogs Trust says that in the first few days you also need to update the microchip details, organise pet insurance and register with a vet. In England, a dog can't be passed to a new keeper unless it's microchipped (or a vet has certified it can't be), and the new keeper must record their name, address and phone number with the database, unless it's already been done for them.
Many rescues transfer the record for you, but check. Ask for the chip number and which database it's on, then follow our guide to transferring a microchip to a new owner, which has each database's steps and fees.
In public, your dog must wear a collar with your name and address on it or on a tag. Our free what to put on a dog tag page helps you get the engraving right.
Keeping them safe while they settle
A new dog doesn't know your area or the way back to your house, and a frightened dog may bolt if they slip their lead (what happens if a dog gets out). Until they're settled:
- Keep them on the lead on walks, and practise recall somewhere enclosed first.
- Check the collar or harness is snug enough that they can't back out of it.
- Keep the front door shut while they're loose in the house, and stay with them in the garden.
- Take a few clear, recent photos, just in case.
If they go missing
Start our lost dog checklist straight away, and tell the rescue too: they may know how your dog behaves when frightened. A QR code dog tag on the collar means whoever finds them can reach you in seconds.
Quick answers
What should I do in the first few days with a rescue dog?+
Let them settle at their own pace in a calm home with a quiet safe space, avoid visitors, keep walks short and in the same place, and update their microchip details, register with a vet and sort out insurance, as Dogs Trust advises.
Does a rescue dog need a new microchip?+
No. In England a dog must be microchipped before it can be passed to a new keeper, so a rescue dog will already have one, unless a vet has certified it can't be. The record must be in your name, though, so ask for the chip number and which database it's on, and transfer it.
When can I let my rescue dog off the lead?+
Not until they're settled, know you well and come back reliably when called. Practise recall somewhere enclosed first.
Does my rescue dog need an ID tag?+
Yes. In public, the law says a dog must wear a collar with the owner's name and address on it or on a tag.
