I don't kow for certain and I never said THEIR puppies come from a puppy mill. All I am saying is dogs from the Humane Society make very good pets, that is of course if you don't want the prestige of registered papers. The only way puppy mills are going to be put out of business is if people quit buying at stores that are supplied by mills. If you have never seen a puppy mill I suggest you google it. It will make you sick. The police records in the paper list animals that are brought in to either the vets or the humane society and several times they are brought in by the State of Kansas from puppy mills. Pathetic that people have to make money raising aminals this way. Have your animals fixed, they make better pets and then you don't make more unwanted pets that have to be put to sleep because the shelter has no room for them.
