As much as we'd like to think our pooches are smarter than the average dog, chances are they're lacking in the brains department like the rest of them. Not to worry, these little guys can get a mental boost through Intelligence Games for Dogs ($30 - 40). Hide treats in the compartments, twist the game and let your dog figure out where it's hiding. Pick the game that's best for your dog's current level of smarts - from easy to most difficult. Great for dogs with separation anxiety, as they spend the entire time you're gone trying to get that damn treat!
