Grey wolves are wild animals that look like big, gray dogs. They live in many different places around the world, from forests to deserts, and even in cities. Grey wolves are very powerful and fast, and can run up to 40 miles per hour. They have sharp teeth and big ears, so they can hear and smell things from far away. Grey wolves usually live in packs, which are families of wolves that look out for each other. They hunt together to catch animals like deer and moose, and then share the food. Wolves can also howl to talk to each other and keep in touch.
