Accueillir un chien de refuge : à quoi ressemblent vraiment les 30 premiers jours

The 3-3-3 rule is a general timeline for how rescue dogs adjust to a new home: 3 days to decompress from the shock of a new environment, 3 weeks to learn the household routine, and 3 months to fully settle in and feel at home. It's a helpful guideline, not a strict schedule — every dog adjusts at its own pace.

Most rescue dogs show real comfort within the first month, but full adjustment often takes closer to three months. Older dogs or those with a harder history may take longer. Patience and consistency matter more than speed.

Hold off on formal training during week one. Give your dog space to decompress first. Once they're calm enough to engage, usually by week two, short, low-pressure sessions using treats as positive reinforcement work best.

Schedule a vet visit within the first month, even if the rescue organization provided records. A baseline exam, heartworm test, and vaccine history review help confirm your dog's full health picture once they've had time to decompress.

Yes. Many rescue dogs seem subdued or cautious at first and become more expressive, and sometimes more particular about things like food or toys, once they feel safe. This shift usually means your dog is comfortable enough to be themselves, not that something went wrong.
