When dogs chase cars, they can end up in some scary and dangerous situations. If you’ve ever wondered why your dog engages in this risky behavior, there are a few possible explanations to consider.

They think it’s a game

Many dogs love playing fetch with a ball or a stick and could happily do so for hours on end. Some of these dogs also have the desire to play fetch with or chase after other fast-moving objects, including cars.

They follow their herding instinct

Herding dogs, such as the border collie and Shetland sheepdog, were bred to round up livestock. If you have a herding dog, they may run after a car because they think the car is separating from the herd, even if they’ve never worked on a farm before.

They hunt their prey

Similar to dogs with the herding instinct, some dogs have a strong instinct to chase after their prey. These dogs may mistake a vehicle for their prey and then chase it down with the intent of attacking it.

They are scared

A car can be frightening to a dog, especially if the car is large and loud, like a garbage truck. As such, your dog may run after more intimidating vehicles that come near your home as a way to protect their territory.

How to break the habit

If your dog has chased after cars before, it’s a good idea to contact a Certified Applied Animal Behaviorist or a Certified Professional Dog Trainer. If your dog has never gone after a car but has shown some desire to do so, you can prevent this behavior with the right distractions.

Whenever your dog is interested in a car, have your dog focus their attention on you and give them a treat. Your dog should eventually associate moving vehicles with treats and lose the desire to chase them.
