If I'm to redesign Spike in "anthro" form, I need to know exactly what type of body shape should he have. Should I draw his child state as not so skinny but looks like he can take part in a outdoor sports game because his future self was muscular, or should I make his abit skinny because his other future self was not that muscular? How thick would his torso and limbs be? How skinny is he? Here is a diagram of possible candidates on what I can made Spike's body shape on. With the most pipsqueak on the left and the most jacked on the right. If there's a female model that suits Spike if it were male, I can make a male version of it. But only if the model would suit Spike.

So which of the N's would suit Spike's body size? What type of body should he have if "anthro"?
