The 3-3-3 rule — and how to use it when your rescue won’t eat.

Bringing a rescue dog home is exciting, and it is very tempting to show them everything at once: the neighbours, the long walk, the friends who want to say hello. For a dog who has just lost everything familiar, that is usually too much, too soon.

Shelters and rescue groups often describe the first months with a rule of thumb called 3-3-3: three days, three weeks, three months. It is not a strict timetable, and every dog is different, but it is a useful way to think about what your new dog may be going through and what helps at each stage.

Decompression

In the first days, many rescues are stressed and on alert: where am I, what is this, is it safe? This is not a good time for training or big outings. It is a time for quiet, predictable days.

What this can look like at home: a lot of sleeping, little interest in food at first, hiding in a quiet corner. Give them a calm space, short walks, and time. If the lack of appetite lasts, check in with your vet.

A common reason the first weeks feel hard: we treat day three the way we would treat month three.

Settling

After the first few days, things often shift. They eat a proper meal. They pick up a toy. This is when it is easy to assume the dog you are meeting is the dog you have adopted.

Not quite yet. Their personality keeps emerging over the next few weeks. Keep the routine steady and the days a bit boring. Notes help: what worries them, when they eat, when they sleep.

Bonding

Around the second and third month, a dog who has relaxed may start gently testing the boundaries of their new life. What tends to help:

• Meet new dogs outside on a walk, not in the living room.
• Start training once they have settled, with short, calm, well-rewarded sessions.
• Stay relaxed in public. Dogs pick up on our tension.

Three common mistakes

1. The welcome party. Keep visitors to a minimum for the first couple of weeks.
2. The big walk. A stressed dog usually needs rest, not a long hike to "burn off energy".
3. The early correction. Punishment in the first weeks can teach a dog that the new home is not safe. Reward what you want instead.

A simple starter kit

A long line for safe walks. A snuffle mat or food puzzle. A chew toy that fits their mouth. A quiet bed or crate in a calm corner. Ask your shelter what food the dog was eating and switch gradually. No affiliate links, no sponsors.

And when you are ready, your neighbourhood can help: other owners nearby know the quiet parks, the patient trainers and the good vets. That is what Pethood is for.
