Just a simple sketch of Dora , showing her strong and muscular body type depite her compact size ( 1m 73 cms tall , some short for a german shepherd, compare Dora and Kurfust near Nicolás,as a clear sample
Her strenght becomes even more evident when is training with Marcos , the girl is able to defeat most rivals even with just her hands and specially her legs. She is not muscular like in yanki comics, but her arms and specially her legs have powerfull well trained muscles thanks to years of swimming and diving PLUS the police officer training!

Still, she is strong and have a lot of stamina but is not invincible, specially against her crazy friends Sophie, Tina, Brittany... that are very very good in bondage tactics https://www.furaffinity.net/view/43816216/ https://www.furaffinity.net/view/38795394/ https://www.furaffinity.net/view/47799570/
If you compare The G4 main bodies you can see easily differences between their body types, being Kurfust the most "muscular", Marcos by far the skinny of the group and Breihzlander the most "chubby" https://www.furaffinity.net/view/50254712/ https://www.furaffinity.net/view/37818333/ https://www.furaffinity.net/view/40596813/
