adoption a dog

DS: Is this slogan or saying include dog adoption pure breeds as well as Pet Store / Dogs BYBr? Your opinion?
I know many of you have heard the song or the adoption saying, do not buy while animals die protection. To me this does not exclude a pure breed dogs, ie the way to stop potential buyers of purebred dogs purchase the confidence and persuade farmers to purchase a home? Is it wrong or is against of good manners to buy a dog when you know that millions of shelter animals are dying.?
I saw this slogan many times on the website PETA. I think that goes for all dogs. I think the message is therefore not buy * any * dog, even a dog bred for a purpose. I find this ridiculous, as if I wanted that the best sled dog, I'd like to go to a reputable breeder * *. * And its my choice whether I buy or adopt.
