How I learned about puppy mills

I found out what puppy mills are when my mom was watching ''Madonna of the Mills'' a movie on puppy mills. I realized how harmful they can be to the dogs. I wanted to do some thing about it. Later that year my fourth grade class got to pick a problem that we wanted to do something about. I thought puppy mills would be a great topic to pick. I decided to make a blog about puppy mills because I wanted to create awareness. So I did my research and became an expert on puppy mills. The most surprising fact I found was the most common place for puppy mills is in Pennsylvania. Thanks for all the feed back!!!!!!!!!!!!!!!!!!!!!!!!!
