Meek, affectionate, aristocratic, yet deadly on the chase, it’s a polite hound that comes alive in the presence of prey; clean, gentle, elegant in form and movement, it’s never vulgar or overwhelming in gestures.

Greek Harehound
Like other scent hound breeds, the Greek Harehound is independent and strong-willed at times. Males in particular require a confident owner to be in charge. These dogs can also be stubborn and impatient at times, so they should be trained at an early age. Positive reinforcements and proper discipline is necessary when training a Greek Harehound and rough handling should be avoided.[3] Due to their original hunting purposes, the Greek Harehound is vocal and extremely loud, and may enjoy chasing small animals and moving things. They may also show destructiveness when bored or left alone for a prolonged period of time.

Molossus
"Never, with them on guard," says Virgil, "need you fear for your stalls a midnight thief, or onslaught of wolves, or Iberian brigands at your back." Aristotle[7] mentions them in the history of animals and praises their bravery and physical superiority. The Molossian breed was most certainly a very large dog similar to the Mastiff we know today.
Who knew Virgil was racist about hispanics?
