Here are some appearence and size references for the Were's. So Bears are about three times bigger then the canine and feline families. Polar bears and grizzlies being one size bigger then that since they are the biggest bears. Canines and felines vary...such as...a wolf is the biggest of the canines and so is bigger in all animal forms then say a fox or dog. But about the same size as a leapord or cougar. Which leaves the tigers and lions being two times the size of a wolf. If this logic does not make sense let me know and I will pm you better details.
This is a good one for the general appearence of a wolf.
Here is a good one for the female..as you can see ONE pair of breasts not many and though she is muscled and powerful she does not out size the male and is still quite femanine.
Here is a good one for size for a wolf..you can tell that when he stands he towers over her. And one paw is enough to cover her backside.
Here is a good one for just their wolf form. In their build and all, but remember they are as tall as a horse is at the shoulder.
Here is for the gernal idea of the cat family. Keep in mind his hand looks weird because his claws are retracted.
Here is one for the bear family... This is the best I can do, but you get the idea big bear with human like hands and such.
