Preventing a Dog Fight When Encountering an Off-Leash Dog

Unexpected encounters with off-leash dogs can escalate quickly, especially if one or both dogs are reactive, fearful, or overly excited. Being prepared with the right tools and tactics can help you defuse the situation and keep your dog — and yourself — safe.


🔧 Tools to Carry

These items can help you safely interrupt or prevent a dog from approaching:

1. Treat Pouch with High-Value Treats

  • Use to distract either dog with a toss-away technique.
  • Always carry smelly, soft treats like hot dogs or freeze-dried liver.

2. Pet Corrector (Compressed Air Canister)

  • Emits a loud hiss that can interrupt a charging dog’s approach.
  • Use with caution — may also startle your own dog.

3. Umbrella or Walking Stick

  • A pop-open umbrella can create a visual barrier.
  • A stick (used defensively, never to strike) can help create space.

4. Deterrent Spray (e.g., Spray Shield)

  • Citronella-based and safe for animals, this can be sprayed toward the approaching dog to deter without causing pain.

5. Slip Lead or Extra Leash

  • In case you need to gain control of the other dog (only if safe to do so).
  • When used in a windmilling motion may deter the approaching dog.

🧠 Tactical Responses

Understanding how your own dog will act if they encounter an off-leash dog can go a long way in keeping you safe.  Minimizing the risk of exposure by modifying where or when you walk them, getting them fit for an appropriate sized muzzle, building strong behavioral skills and/or bringing along another person to help buffer are all ways to help increase the safety of your dog and the public.

If you do end up getting rushed by an off-leash dog:

1. Assess the Situation

  • Quickly gauge the body language of both dogs.
  • Look for signs of tension: stiff body, tail up and rigid, direct eye contact, or raised hackles.
  • Assess the risk level:
    • Low risk level: stay calm and move to safety
    • High risk level: prepare for defensive handling and to break up a dog fight if necessary.

2. Avoid Direct Confrontation

  • Do not stare at the approaching dog.
  • Avoid letting your dog fixate; use cues or treats to redirect.

3. Create Space and Use Obstacles

  • Move behind a car, trash bin, tree, or bench to block the approaching dog’s line of sight.
  • Cross the street or turn and walk in the opposite direction if time permits.
  • Don’t turn your back on or lose sight of the oncoming dog while you create space.  You can’t stay safe from what you can’t see.

4. Toss Treats Behind the Approaching Dog

  • Throw high-value treats behind the off-leash dog to momentarily redirect it.
  • Use this window to calmly exit the area.

5. Use a Firm, Loud Voice

  • Yell a cue like “Stop!” or “No!” or “Sit” to startle the dog and buy time.
  • This may work if the dog has basic obedience training or is startled by tone.

🚫 What Not to Do

  • Do not pick up your dog — this can make them a target.
  • Do not run, scream or flail your arms — can escalate tension.
  • Do not reach between fighting dogs — serious injury risk.
  • Do not try to secure the dog – If you want to help secure the dog make sure your dog is safely contained (in your car, house, or with a friend behind a secure barrier) before making any attempt to secure the off-leash dog
