Almost all pet stores buy from puppy mills, even if they say they don't. Just ask to meet the breeder and see their reaction. Too many pros to mention ... they just love you and you love them back.
Cons: People should consider an adult dog more often. My last terrier-cross was adopted at 4 years old and lived to be 17 years! I now have two from the Humane Society, they make life more hilarious.
