What should I do in the first 24 hours after adopting a dog?

Keep things calm and quiet. Set up a safe space, offer water and food, avoid overwhelming introductions, and let your new dog decompress at their own pace. Follow the 3-3-3 rule: 3 days to decompress, 3 weeks to learn your routine, 3 months to feel at home.

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

The 3-3-3 rule is a general guideline for newly adopted dogs: the first 3 days they may feel overwhelmed and shut down, after 3 weeks they start settling in and learning routines, and after 3 months they begin to fully trust and bond with their new family.

How do I help my newly adopted dog decompress?

Give your dog a quiet, comfortable space of their own. Limit visitors and new experiences for the first few days. Keep a consistent routine, use calm energy, and let the dog approach you on their terms rather than forcing interaction.

What should I feed my newly adopted dog?

Start with the food the shelter was feeding to avoid stomach upset. If you want to switch foods, do so gradually over 7-10 days by mixing increasing amounts of the new food with the old food. Establish a consistent feeding schedule.

How do I walk a newly adopted dog safely?

Use a properly fitted harness and keep walks short at first. Let the dog sniff and explore at their pace. Avoid dog parks and crowded areas initially. Always use a leash and ensure collar and ID tags are secure.
