He was so good in the car. Walked straight in, had a look round the kitchen, took himself off to the bed you’d put down and slept most of the evening. Two days in you’re telling people he’s the easiest dog you’ve ever had.
Then week three arrives and there’s a different animal in the house – one who barks at the postman, who won’t be left in a room on his own, who has opinions about the cat that he definitely didn’t have on Tuesday.
Nothing has gone wrong. This is the normal shape of it, and knowing that in advance saves a great many people from concluding, at around day twenty, that they’ve made a terrible mistake.
The quiet dog in week one is usually shut down
A dog arriving in a new home has lost everything familiar in a single afternoon. The smells, the sounds, the floor surfaces, the people, the routine, whatever he’d worked out about how his previous life operated. All of it, at once.
The common response to that is not to explore. It’s to go very still and do as little as possible until there’s enough information to work out what the rules are. Behaviourally it looks like a calm, well-adjusted, undemanding dog. Physiologically it’s closer to the opposite.
You’ll sometimes see the tells if you’re looking. He sleeps a great deal but wakes at every noise. He eats, but not with much enthusiasm. He follows you with his eyes rather than his feet. He doesn’t play, doesn’t investigate much, doesn’t do any of the low-level pottering a settled dog does all day.
The point of the first fortnight is to bring that baseline down rather than to find out what he can do. That means a genuinely boring couple of weeks, a predictable shape to each day, somewhere of his own to retreat to, and whatever quiet support helps him get there – plenty of sleep, food he can digest, and something like Relaxing Dog Treats fed daily from the day he arrives rather than started later once problems have appeared. You’re aiming to lower the water level, not to test how well he swims.
The three-three-three rule, and what it’s worth
You’ll come across this within about five minutes of joining any rescue group. Three days to decompress, three weeks to start settling, three months to feel at home.
It’s worth knowing, with a caveat: it’s a rule of thumb that somebody made up because it’s memorable, not a finding from a study. Plenty of dogs take considerably longer than three months, particularly the ones from long kennel stays or from abroad. Some are genuinely at home in a fortnight.
What it’s useful for is setting expectations in the right ballpark and stopping people from panicking in week three. What it isn’t is a timetable your dog has agreed to.
Make the first fortnight boring
The instinct is to show him his lovely new life. Take him to the pet shop and let him choose a toy, get him to the beach, introduce him to the family, get some photographs.
Resist all of it. Every new experience in the first fortnight is another thing to process on top of an already full plate.
No visitors, or at most one calm adult who ignores him. No trips out beyond quiet lead walks in the same couple of places. No dog parks, no meeting other dogs on lead, no pubs, no garden centres. No baths unless something has gone genuinely wrong. No training classes.
Short walks are fine and useful – twenty minutes somewhere quiet with plenty of sniffing does more good than an hour somewhere busy. Some dogs won’t want to go out at all for the first few days, and that’s fine too. The garden will do.
He is more likely to bolt now than he ever will be again
The first two weeks carry a real escape risk, and it’s the thing rescues worry about most.
Keep him on lead outside, without exception, including in the garden if the fencing isn’t certain. Use a well-fitted harness with two attachment points and a double-ended lead clipped to both – a frightened dog can reverse out of a collar in about a second and a half.
Check the garden properly, at dog height, including under the shed and behind the compost bin. Put a note on the front door so nobody opens it without knowing there’s a new dog in the house.
Get the microchip transferred into your name immediately rather than when you get round to it, and put a tag on him with your phone number from the first day.
Let him come to you
The hardest instruction to follow, particularly for children, and the most important.
Don’t approach him when he’s on his bed. Don’t hug him, don’t lean over him, don’t hold his face. Don’t wake him for anything. Sit on the floor and read a book and let him decide whether he’d like to come over.
A dog who chooses to approach you is telling you something. A dog who’s been approached has had no say in the matter and is simply putting up with it, and dogs who spend a fortnight putting up with things sometimes stop putting up with them quite suddenly.
Hand feeding is a good bridge if he’ll take it. Sit sideways on, don’t stare, drop bits of food nearby rather than offering them from a held-out hand.
Tummies, toileting and sleep
Loose stools in the first week are close to universal. Stress does it, changing water does it, changing food does it. Keep him on whatever the rescue was feeding for the first fortnight and change over slowly afterwards, mixing across ten days or so.
House-trained dogs frequently have accidents in the first week. It isn’t a training problem and telling him off will set you back a long way. Take him out often, praise him when he gets it right outside, and clean up indoor accidents with an enzymatic cleaner rather than anything with ammonia in it.
Expect a lot of sleep. Dogs coming out of kennels are often profoundly sleep-deprived – kennel environments are loud, lit and unpredictable – and some will sleep almost solidly for the first week. Let them. It’s the most useful thing happening.
Week three: the real dog turns up
Once he’s decided the house is probably safe, he starts behaving like himself. That’s a good sign, even though it very rarely feels like one.
What surfaces varies. Guarding of food, toys or particular spots. Barking at the door. Following you from room to room. Reactivity to other dogs on walks that wasn’t there before. Counter surfing. An inability to be left alone.
None of this is your fault and none of it means the dog is going backwards. It means he’s relaxed enough to have opinions, and now you can actually start working on things – which you couldn’t have done in week one, because the dog you were living with then wasn’t really him.
The other thing that shows up around now is testing. Not dominance, whatever anyone tells you, just a dog working out what the rules are in this house. Answer consistently and it settles quickly.
Routine does the heavy lifting
More than anything else you’ll do, a predictable day builds confidence. Roughly the same times for food, walks, and bed. Roughly the same shape to the evening.
It doesn’t need to be rigid. It needs to be recognisable, so that within a fortnight he can predict what’s coming next, and a dog who can predict what’s coming next has considerably less to worry about.
Start basic training once he’s settled – after the first couple of weeks, not before. Keep sessions to a few minutes, keep them rewarding, and use them to build a relationship rather than to fix anything.
If there’s already a dog in the house
Do the first introduction outside and on neutral ground, not in the hallway. A walk side by side with a person on each dog, starting a good distance apart and closing up gradually over twenty minutes, works far better than a face-to-face meeting in a doorway.
Go into the house separately, resident dog first, and pick up anything worth arguing over before either of them gets there – bones, favourite toys, both food bowls, the good bed.
Feed them in separate rooms for the first month. Not near each other, not in the same room with supervision. Separate rooms with a door between. Most inter-dog problems in new households start over food and most of them are entirely preventable.
Give them both somewhere to be apart, and separate them when you’re out rather than hoping. Expect the resident dog to be unimpressed for a fortnight – grumbling and moving away are normal and healthy communication, not a sign it’s going badly.
Cats want a fortnight behind a baby gate with an escape route and high places to sit, and no forced meetings at all.
When to get help
Sooner than most people do. If there’s growling over food or space, any snapping, real fear of a family member, or distress at being left that goes beyond a bit of whining, get a qualified behaviourist involved in the first month rather than the sixth.
Most rescues will help with this and many have arrangements in place, so ring them before you ring anybody else. They would far rather have that conversation than a return three months later.
Anything physical – limping, skin problems, ears, weight loss, persistent loose stools past a fortnight – gets a vet regardless of what the rescue’s paperwork said.
The three month mark
At some point, usually without your noticing the day it happened, he’ll be lying on his side in the middle of the kitchen floor with his legs out while you cook, and you’ll realise he hasn’t lifted his head at any of the noises.
That’s the thing you’ve been waiting for. Not obedience, not tricks, not a dog who does everything right. Just a dog who has stopped keeping an eye on the exits.
