Why does the dog chase cars?

When a dog starts chasing a car, it's not just frustrating, but it can also be extremely dangerous, so it's important to take decisive action against it.

While chasing a fast-moving car may not seem like a great idea for humans, from the dog’s perspective, it’s a different story altogether. True, not every dog does this, but the desire to do so probably lurks in all of them.

Therefore, the dog cannot resist chasing the car

“Chasing is an instinctive behaviour for dogs” says Samantha Mountain, a professional dog trainer. According to the expert, even puppies aren’t behaving incorrectly when they chase a car. They’re simply following their nature.

This behavior can also be seen as a kind of predatory instinct triggered by movement—especially when the object is moving quickly past the dog. But even if your pet stops chasing and doesn’t attempt to attack its target, it’s important not to allow this behavior, as it can still pose a danger to them.

Some dog breeds are more prone to chasing than others. Terriers and Border Collies, bred for hunting and herding, for example, have stronger hunting instincts.

This is how to stop it

There are training methods that can help curb this dangerous behavior. But before doing anything else, consider whether your dog is getting enough exercise. “A dog whose daily exercise needs are not met can be full of energy that it can use for chasing”, warns the dog trainer.

It’s best to start training the dog at home or in the yard, or in any other place without distractions. The key is to gradually expose them to more and more moving objects and people, and then cars. The latter should always take place away from busy streets, in a quieter location.

It’s important to keep the dog on a leash whenever you take them for a walk, and stick to positive reinforcement methods, such as praise.

Punishment may suppress their behavior for a while, but it’s more likely to make your pet continue chasing cars later on.

Tips for training your dog

Use training methods that provide the necessary control to quickly stop your dog’s sudden urge. “The emphasis should be on impulse control,” explains Mountain.

The expert recommends conducting recall training, which signals to the dog using a command (or in some cases, a clicker).

By giving an immediate cue when the dog is overcome by the urge to chase instead of going after the car, they can return to you.

You can try verbal cues like “leave it” and “watch me.” With the first command, the goal is for the dog to stop what they’re doing and return to you, while with the second, you want them to look at you and turn towards you.
