You know, even though you feel really guilty, probaly 3 quarters of the world don't know they purchased puppies from puppy mills. Trust me on this, I bought a puppy (not from a puppy mill) and I showed her to my friend's dog. I asked where she got her dog from, she said Petland. Then a few weeks later, a email said that Petland supports puppy mills and that's where they were getting the puppies from. I sent my friend the email and she replied back to me and said she never knew about it and that she said she feels so bad buying from perland, supporting the puppy mill. (No lie!) But the positive thing is that you rescued her and brought love into her life. The only thing you can do now, is just sign pietitions, because the person where you bought your dog from, must have left you no clue where they are right now.
