I usually warn new puppy owners to not take there pups out in public until all their shots are done. I believe most breeders do too. Yesterday while I was at the park with Molly there was a guy walking around an 8 week old labradoodle. I just stayed as far away from them as possible. Several years ago I went to the dog park with one of my dogs and another pet owner thought it was sooo cute to bring there 8 week old puppy. Ended out they lost their puppy to Parvo a few weeks later. It just upsets me to see this.
