What is a house dogs predator?

Answer 1

Coyotes are perhaps the most common predator of domestic dogs; a pack of coyotes can kill even a Great Dane or mastiff. Hawks and falcons will predate on small dogs, such as Yorkies and toy poodles. Hunting dogs, including beagles and Norwegian Elkhounds, are at risk of attack from wolves, in certain areas. Dogs that live in very rural or heavily forested places may be attacked by cougars. Even raccoons have been known to kill hunting hounds, although this behavior is usually a defensive measure.

Certain large dogs, such as Pitt Bull Terriers, mastiffs, Rottweilers and Doberman Pinchers, will attack and kill small dogs, which they mistake for prey.
