Omg. xD In the german Movie, they have a different name. Because, 'Tod' isn't a name and you know, for Kids Movie, this is not a good name. xD Cap is the Fox and Capper the dog. But to call a male Fox Dog, is stupid. °xD
Well it is a name lol. The name " Todd " is used on people. Copper is the original name, I Assume because of his rusty brown color. And it's scientific? so..
