Why Does My Dog Bark and Lunge at Other Dogs and People?

Teach your dog behavior options

Outside a business building, a German Shepherd Dog lunges front feet off the ground and growling at some unseen thing or person. The hand of a handler holds the leash tight
A large dog loose inside a car lunges with mouth open at the driver’s side closed window.
Angry lunges can grow from the restraint a dog feels by a closed window to get at something.

Why Dogs Bark and Lunge

  • Dogs may be afraid and want the other dog or person to move away. 
  • Dogs restrained by a leash, fence, window, or vehicle may become frustrated because they cannot investigate or greet. 
  • Barking and lunging are often the dog's attempt to change what is happening in the environment. 
  • Some dogs are alerting their family to something new or unfamiliar. 
  • Dogs that lack positive social experiences may not know calmer ways to respond.

What to Avoid

  • Punishing the barking and lunging.
  • Failing to recognize what stimulated the barking and lunging. 
  • Not teaching the dog alternative behaviors.
  • Waiting until the dog is already barking before trying to intervene.

Dogs usually use the least amount of force necessary to solve what they perceive as a problem. Barking and lunging are often attempts to communicate before behavior escalates.

A small dog has pulled to the end of the leash held by a shopper. No lunge as the dog pauses to study the unforeseen object.
It is appropriate for a dog to acknowledge things the dog sees, but lunging to investigate is not necessary.

What Can Help

  • Recognize that barking and lunging may be the only strategy your dog has learned for handling the situation.
  • Teach your dog response options.
  • Reward the dog for responding with those options in presence of the trigger.

Summary

Barking and lunging are often signs that a dog is uncertain, fearful, frustrated, or simply unsure how to respond appropriately. Rather than asking only, "How do I stop the barking?" a better question is, "Why does my dog feel the need to bark?" Understanding that answer allows you to teach calmer, more confident behavior.
