Jack, saw this on another site...you're probably aware of it, but thought I'd send it your way. Cary For those of you that feed their dog Purina Pro Plan or Purina Hi Pro, the Ruffed Grouse Society receives money from Purina for the weight circles on the bags of food. People would send the weight circles directly to the RGS headquarters for the RGS to receive the money. There is supposedly more info about the program on www.ruffedgrousesociety.org and the name of the program is the Purina Conservation Program. I noticed it in a RGS magazine. There is a form to fill out but I am sure there will be one available to download on the RGS website.
