Wolves (General): Although very similar in look to an Alsatian, they have a broader skull and longer ears. They also have a bushier tail, a long nose and legs. They look lean and rugged like a coyote, but they tend to carry their tails higher.

The Gray Wolf: They are the largest and most common type of wolf, ranging in size at 2-2.5 ft tall and 4-5 ft long. The males are about 100-175 lbs. Females are slightly lighter. Unlike common perception, they are not as large as they seem as a result of their thick fur. In fact, they are about the size of a good-sized Alsatian. Moreover, although they are known as The Grey Wolf, their coloration can vary from pure black to pure white, and through gray and brown, or a combination.

The Red Wolf: This is the smallest of all the wolves. They usually weigh 50-70 pounds and stand to about 51-81 cm (20-32 inches) tall to the shoulder. They usually have a reddish-brown coat, and are smaller than the gray wolf.
