I think when people say don't buy from a pet store and reference sick puppies most likely they mean that pet stores keep puppy mills in business and puppy mills are infamous for having sick dogs on the premises. Many of those sick dogs are bred or used as studs and many of the sick puppies never make it to the store because they die enroute or before they ever leave the mill. Getting a puppy that may or may not be sick is just one of many reasons not to buy from a pet store. I'm sure that a lot of us know or have known someone who bought a dog from a pet store and everything seemed to turn out fine, but that doesn't take into account the poor puppy's parents, or grand parents.

I'll quote Maya Angelou "you do what you know and when you know better you do better."
