If your pet seems to be called to chase anything with wheels, you might be left wondering, "Why do dogs chase cars?"
It's not like they can outrun them, and even if they could, how would they benefit from the end result? The behavior seems strange to say the least, but now you're curious. What causes a dog to chase cars? Let's take a closer look at what may be causing this behavior and how to stop a dog from chasing cars.
Why Do Dogs Chase Cars?
Although humans may not quite understand it, for dogs, chasing is an instinct. For dogs, moving vehicles may be an annoyance, a thrill or something else entirely, but one thing is for sure: It sparks that natural instinct in which a dog recognizes the vehicle as prey they must run after and capture.
And it's not just four-wheeled on-road vehicles, like cars or buses, that your dog might chase. There are other-wheeled vehicles that a dog might be just as motivated to follow, such as bikes, scooters or mopeds. Your dog may even chase people on Rollerblades or in wheelchairs!
Because chasing is a natural instinct, any type of dog breed may feel the drive to chase a car or other-wheeled form of transportation. However, the American Kennel Club (AKC) reports that sighthounds of all sizes and other herding breeds may be particularly driven to chase.

The Dangers of Chasing Cars
One of the most important things to keep in mind if your dog is chasing a moving vehicle on- or off-roads is that if they continue to chase, they might get hit. A collision could cause serious damage to your pet — damage that could potentially be life-threatening. If your dog is chasing and has problems with aggressive behavior, you also have to worry about your pet potentially attacking someone if they're able to catch up to them — like someone on Rollerblades who was simply skating by your property.
