Bringing home a rescue dog goes best when you keep the first days quiet, small and predictable, and treat the dog as an escape risk until it trusts you. Set up a safe space before pickup, put an ID tag on the collar, use two points of leash attachment, and give the dog weeks, not hours, to settle. Most of the hard parts (accidents, shyness, hiding) are normal and fade with routine.

October is Adopt a Shelter Dog Month in the US, according to the ASPCA, so plenty of families are doing this now.

How do I prepare my home for a rescue dog?

Get the basics ready first. The RSPCA's checklist covers a bed and bedding, food and water bowls, toys, a leash, collar, harness and an ID tag.

Hide or secure cables, trash cans and anything chewable. Battersea suggests baby gates and closed doors for rooms that are off-limits.

The RSPCA says the fence should be too high to jump and free of gaps, because a large dog can squeeze through a surprisingly small hole. Remove plants that are toxic to dogs, too.

Keep the dog's shelter food at first. To switch, mix old and new over a few days.

Agree on house rules as a family before day one. Is the sofa allowed? Who does the 6 a.m. walk?

What should I do on the first day with a rescue dog?

Go straight home. The Lost Dogs' Home in Melbourne advises no stops, since the dog is already confused.

Let the dog explore the yard (on a leash), then sit calmly indoors while it sniffs around. Don't follow it from room to room.

Show the dog its safe space: a bed in a quiet corner or a blanket-covered open crate, plus water. Battersea calls it a "safe retreat," not a naughty corner, and nobody should disturb the dog there.

Hold off on visitors. The RSPCA suggests a day or two of settling before walks or visitors, and Battersea says to skip visitors for at least the first few days.

How long does it take a rescue dog to settle in?

Longer than you'd think. The San Francisco SPCA uses a "3-3-3" guideline:

  • Days 1-3: the dog is settling in and may seem scared or withdrawn.
  • Weeks 1-3: a routine forms and the dog starts to show its personality.
  • Months 1-3: trust deepens and the dog feels at home.

The SF SPCA stresses that not every dog follows this timeline. The RSPCA says most dogs take about three months to show their true personality, while some settle in three days.

So if your new dog hides behind the sofa all weekend, it's not personal. Battersea says wanting to be alone at first is normal.

How do I build a routine with a new rescue dog?

Battersea says the first days are about getting your dog used to its new routine. Feed, walk and let the dog out at roughly the same times each day.

Keep the world small. The Lost Dogs' Home recommends quiet streets, the same area each day and gradually longer walks in week one.

Start training early, but keep it light. The SF SPCA suggests short positive-reinforcement sessions and daily enrichment, like a stuffed food toy. The RSPCA warns against punishment, including prong collars and water sprays, because it increases fear and damages trust.

How do I introduce a rescue dog to my other pets and kids?

With children, the RSPCA says kids should stay calm and quiet, let the dog start any contact and leave it room to walk away. A dog rolling over at a first meeting is appeasing, not asking for a belly rub.

With another dog, meet on neutral ground on slack leashes. Walk side by side at a distance, then allow about three seconds of sniffing before calling them apart. Never punish a growl; it's a warning.

With a cat, keep them apart for a couple of days and swap bedding so they learn each other's scent. Next comes sniffing under a closed door, then seeing each other through a baby gate. If it goes badly, step back a stage.

Why is my rescue dog having accidents in the house?

The Lost Dogs' Home says to expect indoor accidents in the first couple of days, since the dog is disoriented.

The SF SPCA says to treat an adopted adult like a puppy for the first weeks: out first thing in the morning, after meals, play and naps, every two to three hours and before bed. Praise and treat outdoor success.

Interrupt an accident calmly and head outside; clean old puddles with an enzymatic cleaner and say nothing. Scolding can make the dog fear you and learn to hide when it needs to go. After two or three weeks with no accidents, the SF SPCA suggests opening up one more room at a time.

How do I stop my new rescue dog from running away?

Plan for it from day one. MaxFund, an adoption center in Denver, says it's not uncommon for a newly adopted dog to run away in its first hours, days or weeks in a new home. Some of its dogs have slipped out the moment the front door opened in their first hour at home. Settling in can take days, weeks or even months, so keep the precautions up until it does.

What helps, according to the Toronto Humane Society and New York's Bideawee:

  • Use two points of contact on walks: a secure collar such as a martingale plus a well-fitted harness, with a leash clipped to each.
  • Keep the dog leashed outside, even in a fenced yard, and skip off-leash walks and dog parks for now.
  • Watch every exit, at home and in the car. A baby gate at any door that opens onto an unfenced area helps.
  • Keep the ID tag on the collar, even indoors.

The microchip only helps if it points to you. The AVMA explains that a chip holds just a registration number, so a scan works only if the registry has your current details. Ask the shelter which registry it uses and put the record in your name the week you adopt.

On tags, the RSPCA suggests your phone number and leaving off the dog's name, since a stranger could use it to lure the dog.

What should I do if my new rescue dog gets out?

Don't chase. The Connecticut Humane Society says a lost dog may be disoriented, so if you see yours, sit down and call softly instead of running after it. Bring treats when you search.

Then act fast:

  • Call the shelter or rescue you adopted from straight away.
  • Contact local shelters, rescues and vet clinics. The ASPCA says to check in with shelters daily, in person, with photos of your dog.
  • Make flyers with a big, bold headline and stick to one design, as the ASPCA suggests, so people remember it.
  • Ask neighbors to check their yards, sheds and doorbell cameras.

You can also post the dog as lost on Paw Alert, our free, ad-free app on Google Play. It puts lost, found and stolen pet reports on a map with local shelters, rescues and vets, and anyone who sees your dog can snap a photo and report it instead of approaching a scared animal.

When should I call a trainer or vet?

Book a vet visit early. The RSPCA suggests a quick "meet and greet" at the clinic first, with treats and attention, so the real appointment is less scary.

The SF SPCA advises seeing a vet if behaviors escalate or you notice poor appetite, lethargy or vomiting.

The RSPCA recommends a qualified behaviorist for aggression, separation anxiety, excessive barking, resource guarding or fear of handling.

Frequently asked questions

What is the 3-3-3 rule for rescue dogs?

It's a rough guide used by groups like the San Francisco SPCA: three days to settle in, three weeks to learn a routine and three months to feel at home. It's a guideline, not a deadline, and some dogs settle faster or slower.

Should I walk my rescue dog on the first day?

The RSPCA suggests a day or two of settling first, with leashed toilet breaks in the yard. Then pick quiet streets, use a harness plus collar with two leashes and keep walks short.

Is it normal for a rescue dog to hide or not eat at first?

Shyness and wanting time alone are common early on. If your dog won't eat, seems lethargic or is vomiting, talk to your vet.

What should I do first when bringing home a rescue dog that's nervous?

Keep things quiet: no visitors, a safe space and a simple routine. Treat it as a flight risk (ID tag on, microchip in your name, two leashes) and let it come to you.
