Chewing, digging, jumping
Why does my dog jump on strangers during walks?
Last updated 23 September 2026 · How we write and check this
Short answer
A friendly dog often jumps at new people simply because meeting someone new is exciting and the walk itself has already raised their energy. Without a taught alternative, jumping is the fastest way a dog knows to get close to an interesting new person.
Novelty and existing momentum
Walking already keeps a dog moving and alert, so a new person appearing adds excitement on top of an already active state, and without training, the most direct way to greet is simply to go straight up and jump.
Not every stranger wants a greeting
Some people are nervous around dogs, allergic, or simply not interested in an interaction, so managing this is about your dog's manners and other people's comfort and safety both at once, not just your own preference.
A default response to strangers
Teach a sit as a default whenever a person approaches, practiced first with friends and family before testing it with people you do not know. Keeping some distance on the lead until the sit is reliable prevents jumping from happening at all.
Key takeaways
- New people add excitement to an already active walk, making jumping more likely.
- Not everyone wants to be approached by a dog, so this affects other people's comfort too.
- A trained default sit around strangers, built up with familiar people first, prevents the jump.
