Dogs do a lot for humans - and today is the day you can thank them! It's National Dog Day! In honor of the day dedicated to man's best friend, we want to see pictures of your pooch! Please do not submit photos more than once! They will not show up immediately because they have to be approved. Because of the number of submissions and duplicate images, it may take a little while for all the pictures to appear. For that reason, we also do not have time to edit the photos, so please make sure they are oriented correctly when you upload.
