Bringing Home a New Dog or Cat: Your First-Week Checklist

The essentials that make settling in calmer for everyone, from the right food transition to creating a safe space your new pet can call their own.

The first week sets the tone for your whole life together. Go slow, keep it calm, and let your new dog or cat decide the pace. Here is everything to have ready.

Before they arrive

  • Food: buy the same food they were already eating, then transition gradually over 7–10 days.
  • A safe space: a bed, crate or quiet room where they can retreat and not be disturbed.
  • The basics: bowls, collar and ID tag, lead, and for cats a litter tray placed away from food.

The first 48 hours

Keep things quiet. Skip the visitors and the big walks. Let your pet explore one room at a time and come to you — resist the urge to overwhelm them with attention.

Build a routine

Predictable meals, toilet breaks and bedtimes help a nervous animal relax fast. Dogs especially thrive on knowing what comes next.

Health first

  • Book a vet check within the first week.
  • Confirm vaccinations, microchip details and parasite treatment.
  • Ask about the right food and portion for their age.

Patience pays off

Some pets settle in a day; others take a few weeks to show their real personality. Calm, consistent kindness is what turns a scared newcomer into a confident member of the family.

Welcome home. The slow start is worth it.
