I was wandering around the internet today and came upon this site http://magdrl.org/. It is one of my favorite sites to go to as it has tons of great pictures of Great Danes that are up for adoption. They are doing a lot of great things and are actively placing dogs all of the time. If you are a Great Dane lover and want your virtual critter fix this is a great place to go. Now I warn you, you might fall in love with one of these great dogs and feel the need to adopt one.
Full disclosure: Ever six months I donate a percentage of the sales from Lucy's Dog House to this organization.
