Accidents after a house move are rarely naughtiness. Your dog has lost the scent map and routine that told him where toileting belonged in the old home, and the new house, however clean it smells to you, carries unfamiliar odours and no history of his own outdoor successes here. Retraining means compressing housetraining back into a few intensive weeks: very frequent outdoor chances, immediate rewards outside, and close supervision indoors so mistakes rarely get the chance to happen.
Why a moved dog forgets what he knew
Dogs learn toileting by location and surface as much as by rule. The old garden, the particular patch of grass, the door he asked at, and the times of day you let him out formed one linked pattern. A new layout breaks every link at once: he may not know how to signal at an unfamiliar door, may be unsettled by new neighbours' dogs marking beyond the fence, and may be drinking or resting at odd times because the move itself disrupted his day. Stress alone loosens bladder control in some dogs, so a puddle from an otherwise housetrained adult is information about pressure, not defiance.
Restart with a puppy-style schedule
Take him out on a lead first thing, after every meal, after play, after naps, and last thing at night, plus hourly while he is awake for the first few days if you can manage it. Go to the same spot in the new garden each time, use one short cue word as he starts, and reward with a treat and praise the instant he finishes outside, not back indoors where the connection is lost. Between trips, keep him in the room with you or behind a gate so you can spot circling, sniffing the floor, or drifting toward a doorway and whisk him out in time.
Confine sensibly when you cannot watch him, using a cosy, appropriately sized area he can keep clean, and return to the rota the moment you are back. If he toilets indoors, interrupt gently if you catch him mid-act and take him out; if you find it later, simply clean it thoroughly with an enzymatic cleaner made for pet accidents so no scent invitation remains for next time, and tighten supervision rather than scolding.
Rebuilding signals in the new layout
Decide where you want him to ask, usually the garden door, and make that route boringly predictable: same door, same lead, same spot. Some owners hang a bell or practise a sit at the door before opening it, building a clear signal he can offer in this house. Walk him on a lead around the garden boundary at first even if it is fenced, because exploring together settles nerves and teaches him this outdoor space is his toilet area too. As accident-free days stack up, stretch the intervals between outings gradually over two to three weeks instead of relaxing everything at once.
When accidents point to something else
Book a vet visit if toileting changes come with increased thirst, straining, blood in urine, loose stools that do not settle, or accidents only at night from a dog who was reliably clean before the move, because infections, gut upsets, and pain can all hide behind a convenient moving story. Also seek help if anxiety signs dominate, such as panting, pacing, and refusing to toilet outside at all in the new garden, since a dog too stressed to go outdoors needs a gentler confidence plan, not a tighter rota.
A shared rota is what keeps this retraining airtight when several people are letting the dog out at different times, and KinsLe supports that through Care Teams, where each garden trip, meal-time outing, and clean day can be assigned and timestamped so nobody assumes someone else has been.
