That link that chocolatepuppy posted is a very helpful site Jadapit. It has literature you can print out in letter form to anonymously send to the houses where you see these dogs penned. There is even a door hanger you can print out. When you go to the site and click on the door hanger, go to the very bottom and in small print it gives an option to print the door hanger instead of paying to order a whole bunch. It may not do any good, but at least you did something to try and help the penned dogs and you never know, sometimes people just need to be educated.
