Many people consider pet adoption more human than buying a pet from a puppy mill. The American Humane Association warns that puppy mills do not breed for good health or temperament and may raise puppies in inhumane conditions.
According to YourDogsFriend.org, federal law does not require breeders that sell directly to the public to be inspected to ensure humane care. Therefore, it is possible that pet adoption is more humane than buying a pet from a puppy mill because it is regulated, and adoption centers often have their own set of requirements that need to be met before they process an adoption.
The American Humane Association claims that irresponsible breeders and puppy farmers may use the Internet and newspapers to reach unsuspecting buyers and often sell to pet stores. To determine whether a puppy has been farmed or brought up in inhumane conditions, the American Humane Association suggests carefully monitoring the number of puppies being sold by the individual, how knowledgeable they are about the breed and how often the parent dogs are bred.
