Free Dog T-Shirt from Pedigree

Pedigree dog foods are well-known for donating a portion of every sale to help homeless dogs,
and now they're offering a nifty "Dogs Rule" T-shirt to pet owners!

It's a mail-in offer, and it does require some UPC codes for proof-of-purchase, but shipping and the shirt itself are free. The UPC requirements apply to their dog treats as well, for those who do not use their foods.
