Wolves are exceptional pack hunters. This is why they are able to take down large prey such as moose or deer by working together as a seamless team. Wolf pups as young as eight months old begin helping on the hunt. Wolves can reach speeds of up to 40 miles per hour when chasing prey, and their thick, double-coated fur enables them to keep warm in even the coldest arctic temperatures. Their large, powerful paws can reach up to 5 inches across and help to propel them quickly across the snow. Read the excerpt from the article "The Necessity of Hybrids":

Grolar bears and pizzlies are the result of crossing polar bears and grizzly bears. These hybrids were first seen in zoos, as the bears' natural habitats did not normally overlap. Recently, these hybrids have started appearing in the wild. Due to climate change, the bears' once-separate habitats are beginning to overlap. Bigger and more aggressive than their parents, grolar bears and pizzlies could pose a risk to natural habitats and humans.

Wolfdogs are, as their name suggests, the result of crossing a wolf with a domestic dog. Bred for the pet trade, these hybrids do not often happen in the wild. Wolfdogs do not make good pets, however, as they can be destructive and aggressive. Many states have outlawed keeping wolfdogs because they can pose a danger to people.
