Here is some useful information to help prevent that from becoming a bad habit.
Car-chasing dogs is a serious problem; more serious than a lot of owners realize. Not only does car-chasing put the dog at risk, but it also puts the car’s driver and many other road users at risk too. Chronic car-chasing dogs often do not live to an old age. We’ve gathered some useful information for retraining your dog not to chase cars, bike riders or runners.
Many owners think that their dog’s car-chasing habit is amusing, and may even joke about it, but they will think otherwise when their dog is injured, or worse if a child or adult is hurt because of their dog’s car-chasing habit. A car-chasing dog will also chase motorbikes, and push bikes. It really is not funny to be chased by a dog when on a bike, and it is far more dangerous to the biker.
Car-Chasing is a totally natural behavior for a dog, as a dog’s natural instinct is to chase anything that moves, be it a cat, rabbit, a jogger or a bike. But the fact that car-chasing is natural does not mean that it should be allowed to happen or even worse become a habit. Car-chasing can and may occur because of a dog’s predatory instincts or out of playfulness, or possibly out of territorial instincts chasing away an intruder. Car-chasing can become a problem with regular callers like the delivery man, the paperboy or the postman, who call regularly. Your dog will soon come to anticipate their arrival and lay in wait for them, chasing them off of the premises; this is a guarding instinct and one that they come to enjoy. If left unchecked, this could even become dangerous to playing children as they run around outdoors. Although the animal would not be chasing them for aggressive reasons, his excitement at the chase may result in injury to the running children who may become scared, possibly inciting aggression by the dog.
If your dog has the car-chasing habit, he should never be allowed to run loose, where he would have the opportunity to chase cars, runners or bikers until he can be controlled by a command from you.
Runners can buy small handheld devices that either emit a very loud noise (anti-attack devices) or emit a high pitch sound that cannot be heard by humans but are not liked by dogs. With an appropriate loud “No” followed by a “good boy” in a friendly voice, and possibly a tidbit, they may deter the chasing dog. It is best to proceed in a walk rather than a run, at least until out of the dog’s sight or range.
Bikers, that are subject to car-chasing dogs, could use similar devices, along with a water-filled spray bottle. Dogs do not like water sprayed into their faces. Bikers are at a disadvantage because they run the risk of falling of the bikes and being injured, plus use of their hands are limited.
Car drivers need to act carefully. Car-chasing dogs do not like the sound of hard braking, and it only has to be applied a couple of times to make the dog weary. This can only be implemented if the dog is beside you where you can see them, or behind you as you drive off. You do not need a lot of speed, but when you can see that the dog is in a safe position, press firmly on your brakes. The sound of the wheels sliding on tarmac, or even better on gravel, will cause the dog to back off. He may come back for a second try, but runs off after a second dose. You will notice that the next time you meet the dog, he will still be interested in “having a chase”, but will be weary and one braking application will send him away.
Of course, the easiest method is to not let your dog run off at all, but for most dog owners, that is an unrealistic goal. Even a well-trained dog who comes on command may decide he'd rather burn off some extra energy with a sprint around town. Keeping your dog interested and happy with what's going on at home, and making sure that he gets some regular exercise, will help keep your dog at home where he belongs!
