They certainly are cute. Love the hair.

The thing about breeding a new purebred is that you're supposed to go out past the 20th generation without ever breeding back to an original pure breed. Anytime a dog is entered into the bloodline it has to be as many generations outcrossed as the rest of them or you'll be taking a step back. Also if you start losing a desirable trait like curly hair after 7 generations and want to breed back to a poodle then you've crossed back to an original and those puppies will then be only 1 generation out. Making a pure breed can take hundreds of dogs and decades of work. Most BYBs just breed out 1-2 generations and thats it. They have no interest in doing the rest of the work.
