The one problem with purchasing a dog is Emotional attachment to the animal. Somepeople the emotion so intense no matter if they know it is a bad buy or not, they almost cannot help it. like a junkie looking for a fix.
So many people want that instant puppy fix, and they throw all the intelligent thought/reasoning out the window at the face of any old puppy. Puppies are cute, and people are great at BS. Couple that with a born sucker who can easily dismiss facts and responsibility for irresponsible action, and there you have it.
You know though, when I read this one of the first things I noticed was it says you want your dog registered with the AKC, UKC, or the National Kennel Club... thbe NKC? I think not, that's as shysty a registry as the ContKC!
