What reactivity looks like

Reactivity is not aggression — though it can escalate to it. A reactive dog responds to a trigger (another dog, a cyclist, a stranger, a loud sound) with behavior that is difficult to redirect: barking, lunging, spinning, freezing, or growling.

Most reactive dogs are not dangerous. They are anxious or overstimulated. The problem for a professional dog walker is that reactive behavior is unpredictable, physically demanding to manage, and can create liability if the dog injures a third party or escapes your control.

Common triggers to note during the meet-and-greet: other dogs, strangers, cyclists, skateboards, loud vehicles, and children. A dog that is reactive to one trigger often has a threshold for others — understanding the full picture before the first walk is essential.

Management techniques that work

Equipment that helps

For reactive dogs, standard collar and leash increases leverage risk. Two alternatives:

Never use a prong collar, slip chain, or choke chain unless the owner has trained the dog on these tools and the dog is fully accustomed to them. These tools require skill to use correctly and can injure a dog if mishandled.

When to communicate with the owner

After every walk where reactivity occurred, send a brief update. Not a novel — one sentence:

"[Dog] had a moment with another dog near the park today — I crossed the street and he settled quickly. No incident. Letting you know."

This keeps the owner informed, demonstrates your professionalism, and creates a record if a pattern emerges. Never downplay or omit incidents. Owners who find out later that their dog had repeated episodes you did not report lose trust immediately.

When to decline the client

You have the right to decline any dog you cannot safely walk. Your contract should include a right-to-refuse clause for exactly this reason.

Decline if: the dog has a history of biting or breaking through harnesses, reactivity is so severe that you cannot safely control the dog near any trigger, or an incident during the meet-and-greet signals risk you are not equipped to manage.

Declining a client who is a genuine safety risk is not a failure — it is professional judgment. Phrase it simply: "Based on what I observed, I don't think I'm the right fit for [dog]. I'd recommend working with a trainer before continuing with a walker."
