Buying a mixed breed is like buying a lucky dip.
You could end up with exactly what you wanted, or you could end up with a broken toy.
I don't want to offend anyone but I prefer purebreds because you pretty well know what they are going to look like and you know the health problems they could end up with.
These days reputable breeders do genetic testing before breeding their dogs to try and ensure the puppies are as healthy as possible.
