"It's like Idefix thinking he's leading Obelix around on a leash."
I don't think I have seen Idefix being on a leash ever .. he just runs around free. And there are indeed many dogs on a leash, who lead their "masters" who just follow behind.
I picked them for their difference in relative size and strength, not to suggest that Idefix would ever accept a leash or because there are other dogs that lead their masters around.
For anyone who is familiar with Obelix but has no idea who Idefix is, it's the original French name for Obelix' dog, Dogmatix. Idefix is a pun on the French expression idée fixe (fixed idea) meaning an obsession.
