You brought your rescue dog home. You expected gratitude, tail wags, maybe a cuddle on the couch. Instead they're wedged behind the toilet, refusing to make eye contact, won't touch the food you bought them. You're wondering if you made a mistake. You didn't. This is decompression, and it's normal.
This guide is the tactical first-3-days playbook. The 3-3-3 rule covers the broader timeline; this is what to actually do hour by hour during the first 72.
What's Actually Happening
In the 48 hours before they arrived at your house, your rescue likely experienced: removal from the foster or kennel they'd started to know, a car ride, handoff to a stranger (you), and arrival at a completely unfamiliar environment that smells, sounds, and feels nothing like anywhere they've been. Their nervous system is in survival mode.
In survival mode, dogs do one of three things:
Hide / freeze
Most common. Under the bed, behind the toilet, in a corner. They become tiny.
Try to escape
Bolt for the door, jump fences, scale gates. The first month is the highest-risk for losing a rescue dog.
Mask & perform
Some dogs seem fine on day one and crash on week two. The “honeymoon period” is real.
All three are normal. None mean your dog is broken. None mean you adopted the wrong dog.
The First 72 Hours, Hour by Hour
Hour 0: Arrival
- • Bring them in on a secure harness + leash. Don't carry them in.
- • Walk them straight to a designated “safe spot” you've set up — small room, crate with door open, corner with their bed.
- • Show them where water is.
- • Take them to the potty spot in the yard or curb on leash.
- • Then: leave them alone. Don't crowd. Don't hover. Don't take photos for social media.
Hours 1–6: Settling in
- • Continue your normal routine quietly. Read, watch TV, do laundry.
- • Don't make direct eye contact. Don't talk to them in baby voice. Don't reach over their head.
- • Offer food: same food they were eating at the rescue/foster. Leave it down 15 minutes, remove if untouched.
- • Take them outside on leash every 3–4 hours for potty breaks. No long walks.
- • If they're hiding: leave them. Place treats and water near the hiding spot.
Hours 6–24: First overnight
- • Last potty break right before bed.
- • Crate or designated room overnight — don't let them roam the whole house yet (escape risk + accidents).
- • If they whine through the night: ignore. Responding teaches that whining gets you. Soft white noise / TV background helps.
- • Many rescues won't sleep their first night. That's OK — they're hyper-vigilant. They'll catch up by night 3.
Day 2: Same as day 1
- • Same quiet routine. No visitors. No new spaces.
- • Most dogs eat by day 2 if they didn't day 1.
- • You may see micro-progress: brief eye contact, sniffing your hand, taking a treat. Reward by NOT making a big deal of it.
- • Don't bathe. Don't introduce to other pets in the home (do controlled intros around day 5–7).
Day 3: Watch for breakthroughs
- • Most dogs start eating normally and showing curiosity.
- • A tail wag, a leaning-in for a brief pet, eating with you in the room — these are the milestones.
- • If by end of day 3 they're still totally shut down (no food, no water, no movement), call your vet for guidance.
- • If you see breakthroughs, keep doing what you're doing. Don't add stimulation just because they perked up.
What NOT to Do (The Common First-Week Mistakes)
Don't throw a “welcome home” party
No visitors, no friends “just stopping by to meet the new dog.” Wait 7–14 days minimum.
Don't bathe in the first week
Even if they smell. A bath in week one is a profound trust violation. Wait until they're settled.
Don't go to off-leash parks
Flight risk peaks in the first month. Calgary off-leash parks are a hard no until week 4–6 minimum, and only after secure recall.
Don't change their food
Stress + new food = digestive disaster. Use whatever the rescue/foster was feeding for at least 1–2 weeks before transitioning.
Don't enrol in daycare or training class
Wait 4–6 weeks. They need to bond with you in your home before adding more stimuli. See the daycare guide.
Don't leave gates / doors unsecured
Most lost rescue dogs disappear in the first month. Double-check fences, never let them off-leash, check gates twice.
Don't take it personally
Your rescue dog isn't rejecting you. They're processing. Time fixes almost everything.
When Decompression Crosses Into Medical
Stress explains a lot, but stress + physical symptoms = call the vet.
- No food OR water in 48+ hours
- Bloody diarrhea or persistent vomiting
- Uncontrollable shaking + cold/wet
- Can't stand or walk
- Honking cough, eye/nose discharge (kennel cough)
- Bloated abdomen, unproductive retching (bloat = ER)
- Seizure or collapse

Frequently Asked Questions
My new rescue is hiding under the bed and won't come out — is this normal?
Yes — the most common decompression behaviour. Don't pull them out. Place treats at the edge of the hiding spot. Most dogs come out on their own within 1–3 days.
How long does it take for a rescue dog to settle?
3-3-3: 3 days to start decompressing, 3 weeks to settle into routines, 3 months to feel fully at home. Personality fully emerges over weeks 4–8.
My rescue dog won't eat — should I be worried?
First 24–48 hours: normal stress response. Use the food they were eating at the rescue. If 48+ hours of no food/water, call vet.
Should I take my new rescue dog for a walk on day one?
Short potty walks only (5–10 min on a secure harness). No long walks, no off-leash parks — flight risk is highest in the first month.
When should I introduce my rescue dog to friends and family?
7–14 days minimum. One person at a time. Let the dog approach the visitor — not the other way around.
What is the “ignore them” technique?
Deliberately not making eye contact, not petting, not talking for the first 24–72 hours. Removes pressure. Most decompressing dogs choose to engage on their own once the pressure is gone.
When should I call the vet during decompression?
No food/water 48+ hours, bloody diarrhea, uncontrollable shaking, can't stand, kennel cough symptoms, bloat. Stress + physical symptoms = vet now.
