I think there is much to be said in the ways of cartooning and art styles of a cartoon nature, but I certainly understand what your saying. Realism is quite wonderful although I've found it quite difficult. Too difficult for me anyways. XD
There are lots of resources out there if you keep your eyes open though.
What I would suggest is investing in a book on form and anatomy, both for humans and animals. Study the forms and how they change in different poses. It will give you really good insight as to how certain bodies work and move, and ultimately look in certain poses.
http://www.amazon.com/Drawing-Human-Body-Anatomical-Guide/dp/080695891XBooks like this are a great way to start, so I'd keep an eye out for any anatomical based sketching books.
Also
http://www.posemaniacs.com/ would be a good place to start too.
I'd say my only advice is to not get frustrated, as realism can be quite tricky and remember to just have fun with it.
I wish you the best of luck, and I certainly hope to see your work someday! Also, welcome to furry.ca! :3
