Your young dog is not being rude when she launches at the door — jumping worked when she was small and people laughed and fussed her anyway. Now that she has adult weight behind that enthusiasm, the same leap can knock a child, scratch an older relative, or frighten a nervous guest, so the greeting itself needs retraining, not just telling her off after she has already jumped.
Why jumping still pays off for her
Jumping gets a young dog exactly what she wants: faces get closer, hands come down, voices go up. Even pushing her off or scolding her is attention, and attention after a jump teaches her that jumping starts the party. The polite alternative has to pay better than jumping does. A calm stand or sit needs to become the reliable way she earns approach, touch, and praise, while a jump quietly makes the interesting person step back and wait. That contrast, repeated calmly, is what changes her choice at the door.
Set the door up so she can succeed
Start with management while she is learning. A lead clipped on before the door opens, a baby gate across the hallway, or a mat she knows well a few steps back from the door all stop her rehearsing the full leap while you teach the new pattern. Ask visitors to help before they arrive: ignore her completely while paws are off the floor, turn slightly sideways, and only greet her when she is settled. Brief tradespeople and delivery callers differently — keep her behind the gate for those brief hellos so she does not practise frantic greetings you cannot control.
Teach the greeting in small, boring stages
Practise when no real visitor is expected. Knock on your own front door, ring the bell, and reward her for going to her mat and settling there. Have a family member come through the door like a guest while she stays on lead, and if she holds her sit, let the guest approach, stroke her chest rather than the top of her head, and step back again. If she jumps, the guest calmly withdraws and you reset without fuss. Short sessions where she mostly succeeds build the habit far faster than one long, exciting rehearsal where she fails repeatedly. Gradually let the lead hang loose, then practise with the gate open, then with friends she knows well before you try her with excitable visitors.
What to watch for as she grows
Some young dogs jump only when they are already over-aroused from play or a walk, so schedule greeting practice when she is calm rather than straight after zoomies in the garden. Watch that children in the house are not secretly rewarding jumps with squeals and wrestling, because one exciting greeter can undo careful work by everyone else. If she is mouthing clothing or cannot settle at all around guests despite several weeks of consistent practice, a qualified trainer watching one real arrival can spot whether arousal, anxiety about strangers, or simple under-practice is driving it.
Consistency at the door is what turns a single good rehearsal into her everyday habit, and KinsLe Care Teams helps by letting you assign the mat, lead, and visitor steps for this dog to everyone in the house so each arrival is handled the same way.
