That is not true. You can’t even find a purebred dog in a shelter nowadays. Only pitts mix and chi mix. Rescues come through and take any adoptable dog to rescue. You may be able to find a shephard mix. It may hav3 true years ago but not now. Just go look for yourself.That's why I'm not a breeder. The cost alone of getting GOOD breeding stock! And the time and effort of becoming knowledgeable about genetics, yikes! And to just breed casually without doing the homework? Nuh-uh. Not when 3 million or so dogs are put down every year bc there aren't enough homes for them, and a good percent of those are purebred, many of them AKC registerable? No. Just, no.
