From your dog's point of view, a new walker is a stranger who arrives, takes her lead and walks her away from the person she trusts. Some dogs accept that instantly; a sensitive dog reads the same event as being handed over by her owner to someone unknown. Tolerance is built by removing the suddenness: she should meet the walker repeatedly in low-stakes situations, learn that this person produces good walks, and only then discover that being left with her is safe too.
Let the first meeting happen on a walk
Skip the front-door introduction, where a stranger entering her territory and reaching for her is the hardest version of the meeting. Meet outdoors on neutral ground and simply walk together. You hold the lead at first; the walker walks alongside, chats, and lets your dog investigate at her own pace rather than crouching over her or offering a hand to sniff. Let the walker scatter a few treats on the ground as you all walk — food arriving without pressure. If your dog is shy, two or three of these joint walks before any handover is not excessive; it is the foundation everything else stands on.
Hand over the lead in stages
On a later walk, pass the lead to the walker while you stay with them, dropping back a few paces, then crossing the street for a stretch, so your dog practises being guided by the walker while you are still visibly around. The first truly solo outing should be tiny: the walker takes her around the block or to a favourite nearby spot while you wait at home, ten or fifteen minutes at most. Judge the stage by how she returns — loose body, normal panting, happy to greet you without frantic clinging. A dog who comes back wound up, drooling or glued to you afterwards is telling you to repeat the shorter stage, not push on.
Give the walker the dog's exact script
A new walker cannot guess the details that keep your dog calm, and inconsistency from a stranger is unsettling. Walk the exact first route together and spell out the specifics: which side she walks on, the cues she knows and the words you use, where she is allowed off lead if anywhere, which neighbourhood dogs she adores and which she must be given space from, what spooks her, how the harness goes on and how the front door routine works. Agree what the walker should do if she balks, pulls home or refuses to go out at all — waiting her out calmly and letting you know beats dragging her round a route she is frightened of.
Build solo time by minutes, and watch the trend
Extend solo walks gradually across the first couple of weeks, varying the walker arrival slightly so your dog does not learn one rigid pattern. Ask the walker for honest reports, including the walks that did not go well; a walker who admits your dog was unsettled is far more valuable than one who says everything is always fine. If she remains distressed after several staged introductions — hiding when the walker arrives, refusing walks, toileting indoors after outings — slow right down and talk to a veterinarian about anxiety, rather than assuming she will simply get used to it. For every handover, give the walker a KinsLe Care Pass so she has temporary, clear access to your dog's routine, feeding and key contacts while you are away, and nothing is left to guesswork.
