Went to an osteology museum today. Feel free to use these as references or for help :3 Just a warning though- some of the pics are a little blurry

Serval

Gray Wolf

Black-Backed Jackal (Couldn't get a clear shot of the gray wolf's back legs. I am not sure that they are exactly alike though.)

Domestic Cat

Domestic Dog

Horse

Cassowary (Dedicated to Creepy_The_Wolf :> ) (You can use the signs in the other pictures for scales. And this bird was a small one o.o )

Enjoy!
