The biggest thing you need to do with any non-human aspect of drawing is understand the anatomy, the skeletal structure and how the muscles are attached to the skeleton in particular. Have some good reference material for that. If you have the time watch footage of the animal in question to see how it moves and how everything in its body is put together. Or even better, interact with the animal in person if possible.

Art imitates life after all.

Once you can see how an animals anatomy is structured and how it moves in your minds eye, getting the basic form in a drawing is much easier.
