Week three is when returns spike

Dogs come home quiet and agreeable, then start guarding furniture or barking at visitors. Adopters think they were misled, but the dog is just getting comfortable.

Week one looks deceptively easy

Shelter dogs have elevated stress hormones for weeks. Cortisol drops over days once they're home, and during that stretch many dogs shut down completely.

“A dog leaving a shelter has spent weeks or months in a loud, unpredictable environment with elevated stress hormones.”

Book a vet visit immediately

Schedule an appointment within the first week to confirm the microchip is registered to you, not the shelter. This matters if your dog gets loose on day four.

Keep the first fortnight boring

No visitors, no dog parks, no car trips, no training classes. Give your dog one room to retreat to and let them come out on their own schedule.

“A dog who has been handled by eleven strangers in five days has no opportunity to decompress.”

The real dog shows up later

Between week two and four, your dog's actual personality arrives. This often includes resource guarding, leash reactivity, or house training regression.

“The mistake is treating week three as proof of a mismatch rather than as the point where the real work begins.”

New dogs bolt frequently

They have no attachment to you yet and no map of the neighborhood. Use a martingale collar or harness, clip the leash to two points, and check fences for gaps.

When to ask for help

A dog that hasn't eaten in 48 hours needs a vet. Any bite or near-bite warrants a call to a behaviorist immediately, not a wait-and-see approach.

“Early intervention works considerably better than trying to tackle it after a pattern is established.”

Boredom builds trust

Two weeks of deliberate boredom gives you a dog who trusts the house. That's the foundation everything else is built on for the next decade.

“Give them the room to arrive properly, and you'll spend the next decade with the version that was there all along.”
