All of this is always a concern to me since I have NO IDEA where Pixel came from!! I got him as a "rehome" when he was only 5 months old and since the lady I got him from advertised him as a "chorkie," I'm afraid he may have been from a "designer dog" puppy mill. I was so worried about him having health issues, but I had all the blood tests done before his neuter, and all the results were good. He will be 1 on 8/25 and is doing great so far (knock on wood). I hate the thought that he may have come from a bad place though
