Most of our dog breeds have some form of aggression in them, since they needed different forms of aggression to do their work: terriers are often aggressive towards other dogs and animals — they were and are fighters, the man working dogs imprint humans as being of their same species so they show the same kind of aggression that they show towards other dogs, the
sight hounds were bred to be killers of game and sometimes other canines, the mastiffs were bred to take down
large game and guard property, the flock guards were bred to be aggressive towards canines, the
hounds were bred to be aggressive towards furred animals, some of the pointers were bred to be able to guard the hunter's game, etc., etc..
Italian Greyhounds (IGs) are the smallest of the
sight hound group, which also includes breeds like the Saluki, Afghan
Hound, and the IG's
larger cousin, the Greyhound.
Both
hound types were selectively bred to hunt a wide variety of animals: Sighthounds were used to find and chase down
large game such as deer, elk, moose, and wild boar; small
hounds used scent to chase prey into the ground; and medium - sized
hounds utilized both
sight and scent for smaller game like rabbits and foxes.
