I guess this is technically not a "cool guy" find, but dog is man's best friend, so work with me here, people. How handy is this little doggie water fountain? Granted, you have to have the kind of dog who can learn how to use it, and possibly be heavy enough to make it work. I'm not sure a chihuahua is going to be able to get this working. And for your sake, I hope you don't have the kind of dog that figures out how to torment you with it. Or a cat. Cats won't be down for this at all. Still, it's a clever idea and would be one heck of a conversation piece when Fido gets the hang of it. $39.50 at Frontgate.
