Featuring important holidays such as National Pet Day (celebrated on April 11) and National Bulldogs Are Beautiful Day (celebrated on April 21), April is a month for dogs. Celebrate the smiles that canine friends bring with Dog Per Day. Launched by dog-loving couple Eric and Kate, the site highlights a new cute canine every day, sure to bring a smile to any visitor's face. On the Gallery page, visitors can view approximately one hundred pictures of dogs (as of this write-up), with captions briefly describing their breed, name, and other key details. Interested readers can even opt to receive a daily email from the site showcasing the featured dog of the day. Interested in submitting your own dog to be featured? There's an option for that, too, by following the instructions on the Submit Photos page. In addition to plenty of "aww" worthy content, the site contains the Dog Blog and Articles sections, which highlight topics relevant to dog owners and enthusiasts.
