I saw this vid:
And this question crossed my mind. The dog in the video seems to be boxer sized... And I wonder if that strategy would work with something a little bigger.... Also, this is obvious, but let me clarify: 'I'm thinking about a FEMALE Great Dane and a MALE Chihuahua. (The other way arround, we would get a Chihuahuaburger before anything even happened... And would be animal cruelty. ) Since they're the same species ( a dog, aka Canis lupus familiaris) that means they can make viable offspring, rigth?
