 Even rescue organizations and shelters provide healthcare and screen potential adopters to ensure that dogs and cats go to a good home. Well, a few years ago, a couple answered an ad about a beagle that the owner would let go at a discount price since it was the last puppy in the litter. The couple met the breeder at a local Walmart and paid $600 for a beagle puppy that wasn't even eight weeks of age. It was much younger than that.
