Chasing or giving chase is one of the most primitive instincts of a dog. A dog chases to fulfil its acute sense of smell and its thrill for the chase. Some dogs’ breeds (hound-dog types) are more prone to chasing, given their basic hunting instinct, ‘prey-drive’, that is mostly found in predators (wolves, foxes, wild dogs). Dogs will pee on cars to mark their territories and when these cars travel through other dogs’ areas, they are chased by them. However, these dogs chase cars only for a little distance, mostly the boundary of their territory.
