Australian Dogtree is a free service that aims to help dog owners find playmates and walking friends for their canine companions. To search for doggie friends, human users can simply enter their postal code; more advanced search options are also available, such as breed and size. Either way, the result is a list of other suitable canine members in their area. Once they find some that seem like a good match, dog owners can invite them through the site for a playdate or meeting. There are currently almost 600 members on Dogtree, and most elect to use their dog's photo and name as their username on the site.
