I can personally guarantee that Sylvia's Pets does not sell puppies from mills. How? Because I work there. I've known the owner for nearly a decade and she would never do such a thing.
It doesn't really matter what I say here, because people are going to believe whatever they want to believe. Human nature tends to notice the nasty, hateful rumors others spread more than anything positive I could tell you. All I can say is that Sylvia's Pets is an honest, local business. I know that's not as exciting as puppy mill accusations and ""dinosaur parasites,"" but it will have to do.
