Named after Documenta, a prestigious art exhibition in its 14th edition in Kassell, Germany, Dogumenta is the first U.S. exhibition made specifically for dogs. (British designer Dominic Wilcox developed an exhibition for dogs in London last year.) The concept might seem like the art world’s equivalent of the talking-animal movie, but as that much-maligned subgenre (in one of its better recent examples, Kevin Spacey voiced a grumpy cat in “Nine Lives”) can teach us something about being human, so the enthusiasm of a dog unfettered by current art trends can teach us to let our aesthetic hair down, so to speak.
