Our dog remembers the location of toys at the park over long periods of time, though being able to sniff them out probably helps. He also expresses genuine surprise and suspicion when he sees novel objects (e.g. the large Christmas tree that was put up in the park, a horse and rider), because he knows they're not usually there. He doesn't like fat people, which is embarrassing, but I also knew a dog as a teenager that freaked out anytime it saw someone who wasn't Asian. Just given the amount of back and forth communication that happens between most owners and their dogs, they're very clever. Cats are some of the best hunters in the animal kingdom, but I've never felt that they're there in the way that dogs are.
