It's National Dog Day, which means everyone has an extra reason to post pictures of their dogs to the internet.

College football has many live dog mascots, so in honor of National Dog Day, we figured we'd dig through the photo files (and Twitter) to find pictures of the many very good dogs that you can find on the sidelines of college football games.

Here are some dog pictures, enjoy.
