When you breed two different breeds of dogs, the offspring will look more like either one breed or the other...it takes successive generations of line breeding to get the pooches to 'breed true'...where all the pups will have a distinctive look.

These designer dogs are just first generation breeding experiments...no better than the Heinz57 at the pound, they shouldn't command hundreds of dollars.

And all I'll say to the comparison of BPs...they are a whole different animal... apples and oranges.
