How many of your dogs have looked like this at the end of a really fun outing? I love this photo. Sana, the big galoot of a dirty dog, is a contestant in Dogster’s World’s Coolest Dog & Cat Show. Check him out in the Naughtiest Dog category. While you’re there, vote for your favorites in that category and others. And there’s still time to submit your own dog and cat photos, so go through your archives or start snapping away!
