I just created the armatures for my dog. This is just a test pose. I may put him in some race of some sort. C&C welcomed.

Looking good 
Couple of observations:
The black circle around the rear leg needs to be removed/reduced.
The belt could be a little tighter, it looks quite loose with the gap at the top.
One word: woosh
Great work. Does have a bit of a black circle around the hind leg.
The dog could probably use more harnass than that.
So, is this a dog used as a guinea pig for a new jet pack invention, or is he/she a seasoned racer? Or maybe a novice jetster? Or maybe an inventer himself…Or he saw it on QVC and decided he couldn’t live without it?
Keep up the great work.

I have made some changes to the picture. I removed the procedural texture that was giving me the heavy black line around the back. I also tightened his belt and added some more stuff. Thanks for the feedback and please keep it coming.

I am sorry for the cut and paste link. My web server is currently down. So, I am using my Tripod account until in comes back online.
Cool. Your going to make this into an animation rite? Awesome work so far!

I would like to make this into an animation, but for now I think it is just going to be a still image. I have some free time coming up soon. So, maybe I can work on this as an animation then.
Very good modelling! I really like it…but those particule could use alot of improvment…try tweaking it a bit. Reduce the alpha, more of add, put the hard at about 50…if it’s less it will look kinda horrible 
Thanks for the comments X-WARRIOR. I will have to give that a try. I have been on a jury for a DUI “Driving Under the Influence” the last two days and have not had a chance to work on any of my Blender projects.
