I think the ASPCA does their best to shut down puppy mills - there are just so many of them. I don't believe they have the resources to go after all of them. If you watch Animal Cops or any of the related shows on Animal Planet, you will see that there are constantly caring people out there doing what they can - but there are not nearly enough "animal cops" out there to make much of an impact. On a positive note, did you see the one last night where they shut down a puppy mill with over 150 dogs? One less large scale mill in operation!
Each Kennel is USDA Inspected once a year. They have certain guide lines the person is to follow. The kennel is graded and them givin the things that they need to fix or change. The Inspector ussually gives them time to bring their kennel up to standards. If the kennel has got alot of problems they are shut down immediately. If they are a good kennel they will comply to the inspectors . The ones that you see are really bad don't even have inspectors come. They have found ways to hide. They can have as many dogs as they wish . Jubilee
