Trouble with the feet

I had been studying the Great Dane model for at least a week, and followed a tutorial that explains how to make the back leg of a dog.

The trick about dog`s back feet are that they have one additional joint in their skeleton.
This means that i would need a different, more complex ikHandle to go from the hip to the foot.

After about a weeks struggle and both me and Georg scratching our heads, i came to the comclusion that the effect i would gain from the tutorials` technique was not worth spending this much time on, so i decided to stick to a normal ikHandle stretching across 3 joints, as opposed to the normal 2 joint.
