Turns out that the whole "cat vs dog" story is just a human invention. They don't necessarilly hate each other or attack one another in nature - you'll never see a wolf going after a lion (since the first would be easily surpassed by the second in the run) or a leopard including wild dogs in their menu (because the dogs travel in packs to defend themselves).
What happens is that dogs, as any predator, pursue smaller animals whenever they see them. The confrontation with cats is more common because, in an urban environment, their encounters are frequent. Different species usually keep their distance from each other, but when they compete for space or attention, things go worse, as it is in the case of houses with cats and dogs.
But keep in mind that cats ARE trying to take over the world next time your fluffy one plays with you.
