I have to chime in here because I know how strong the urge to "rescue" a pet store puppy can be. I have always been against pet stores and won't even buy supplies or food in stores that sell puppies. Yet, for some reason I always have the urge to "just look" when I pass a pet store in the mall. Well imagine how upset I was when I saw the most adorable Great Dane puppy in the pet store one day. He was skin and bones and obviously not being fed enough for a giant breed puppy. I asked one of the employees how much he was being fed and she replied "two cups a day." So obviously he was getting the same amount of food as the poodles and minipins next to him, even though he was over 3 times the size! 
I love Great Danes and my first instinct was to call my husband to see if we could take him home, but thankfully logic took over. I called the ASPCA instead and reported the petstore for underfeeding. If I had taken that puppy home, I no doubt would have loved him unconditionally and he very well could have made a wonderful pet. But by buying him, I would have been contributing to the cycle that makes pet stores and puppy millers profitable. See they RELY on you feeling bad for them, throwing logic aside and wanting to rescue them. That's how they stay in business. Because if people put aside their emotions and think rationally, they would eventually figure out that it's better to go with a rescue or a reputable breeder who does health testing, breeds for temperament, properly socializes puppies, etc.
I still think about that puppy from time to time, but I don't regret for a second that I didn't buy him. If I did, there would have just been another puppy in his place the following week. And the cycle continues...
