Horses and jackasses--mate one way, you get mules, mate another way, you get jennies. West Atlantic Herring gulls--mate east to west, you get viable offpring, mate west to east, you don't. Dogs and cats--mate them, and you get occasional live offpring. Chihuahuas and Great Danes--genetically, they are one species--so you should be able to mate them, and produce viable offspring, right?
I gotta say I'd like to see that too! :-)
You HAVE heard that the Taco Bell dog actually DID get a Great Dane bitch pregant!
Yeah........ The vet said the St. Bernard probably put him up to it...............
