Interesting. But just another misuse of our beloved K-9s to advance the scientific community.
Scraping, impregnating, what's next?
And the interesting comment about the choice of dog that they used to clone? What does that tell you - next they will be using really stupid people to clone for stem cell research? Ooops, did I say that out loud?

For what good purpose is this done? Just because they want to show they can....stupid, stupid stupid waste of education, time & money

It is a ridiculous concept since there is such a voluminous amount of dogs and cats that have to be destroyed on a daily basis!
