Why do terriers run on 3 legs?

I wonder do small dogs realise that they are just that -small or when they see an alsation do they think they are that big also?


Maybe it's an inferiority complex, thinking other dogs are almost as good as them !

You could be right there Graham, my wiry tiny terrier cross has proven quite good at climbing bushes, small trees, fences and walls, as if to say I may be tiny but don't underestimate me!
 
Its an evolutionary thing really...eventually they will be born with just 3 legs.... and that's a fact!
