It does not really matter to me. I generally get dogs that I "feel" for. There are dogs that would "call to you" and dogs that won't. When I touch or carry the dogs, the one that seems to enjoy my cuddling the most gets to go home with me. I do understand that there are many mutts in shelters. Perhaps next time we get a dog, we will go and visit a shelter instead of a pet shop or breeder. Many people go for pure bred dogs because they have more value. It is the only way to sell the pups at a decent price. Since I am not in it for the money, I really don't care if I end up giving puppies away even if they are pure.
