Another dog appears on your walk. What do you do first?

Your dog has spotted the other dog before you have. Their body goes still. The leash feels different in your hand. This is the moment to choose a route, not to deliver a lecture on “sit.”

Dogs Trust describes reactivity as a heightened emotional response that can arise from fear, frustration, overwhelm, pain or other causes. A bark or lunge tells you your dog is struggling in that moment. It does not, by itself, tell you which emotion is underneath. Start with safety and space, then investigate the pattern later.

Scan for an exit before the dogs meet

Look for a side path, a driveway, a parked car you can move behind, or room to cross safely. If the other dog is coming toward you, turn calmly before your dog is fully absorbed by it. Dogs Trust recommends moving away or using a visual barrier when you see a trigger ahead. Keep a secure hold of the lead without adding unnecessary tension. Do not step into traffic, and do not put yourself between two dogs if doing so is unsafe.

If an off-leash dog is approaching, prioritize safe separation and ask the other handler to call their dog. You cannot control whether they do, so keep your own route and exit in view.

Check what your dog can do at this distance

Can they turn with you? Take food they usually want? Look back at you? These are useful observations, not a test they must pass. If your dog cannot respond, create more distance rather than repeating a cue at a higher volume. Dogs Trust recommends giving the dog enough space to relax; VCA describes starting behavior work at a distance where a dog can remain relaxed while another dog is visible.

This is not “letting the dog win.” It is choosing conditions in which learning is possible. The precise distance is individual and may change with the day, the environment, and whether your dog has already had a hard encounter.

Save the training session for a workable setup

Outside the crisis, note the trigger, distance, route, body language, and what helped. Patterns can reveal the quiet times and wide routes that set you up for a more deliberate practice session. For persistent or intense reactions, work with your vet and a qualified behavior professional on an individual plan. Dogs Trust advises a vet check because pain or illness can play a part.

A safer walk need not look impressive. It may be a simple early turn and a dog who can breathe again. Build from that instead of rehearsing one more close pass.
