Stag

Stags are beasts, a type of deer. They are large animals, taller than humans, and have antlers. Most stags are when approached. Despite being herbivores, they are tough, fast, and territorial, and can provide a challenge for any hunter.

Stags are common in forested areas throughout Azeroth. They are targets for humanoid hunters and natural predators like wolves, but their mighty antlers and ferocity make them difficult prey. Stags avoid conflict but can be aggressive in larger groups or when startled.

Stag Meat when cooked becomes Lean Venison.

As a hunter pet
Stags became tamable by hunters as Ferocity pets with the Warlords of Draenor expansion. They feature a wide range of models, including talbuk and gazelles, and possess the Grace (pet) skill when tamed.

In, there will be a much larger form of deer, the moose, in the Broken Isles, and they come in brown, fawn, silvery-white, and black. Keep in mind that moose are only found in Highmountain.

In Warcraft III
Stags appear as critters in Warcraft III: Reign of Chaos. The animated gif from the website is called "deer".

In the RPG
They are particularly aggressive during mating season in the fall, and only at this time are they commonly found with females.
