The Bark in Space: Book 5 (Chicagoland Detective Agency)

"There are hundreds of stories about talking dogs, but if this graphic novel is any indication, every book would be better with a dog in it.
The math is simple: A Google search for 'dog' brings up 1,430,000,000 results. So Raf's newest invention ought to be an instant success. It's a dog-to-human translator. The only problem is, dogs don't have much to say. Even Raf's (alien) canine friend Bradley, who happens to speak English, says: '...much as I love my Earth doggie buddies, I gotta admit that, unlike me...they're kinda dim bulbs....' The storyline is busy, even for a Chicagoland Detective Agency comic. There's a missing princess, a dog show, a mad scientist and a saucer full of dogs from the planet Fnarf III. The alien dogs get the best lines, by way of Raf's iDog2 translator, including: 'Human person, can you throw the flying saucer of playing fetch?' The art looks a bit more rushed than in previous volumes, but this is still one of the most inventive stories in a consistently innovative series. And even human beings will sympathize when the Fnarfian Princess Zu-La says, 'Earth people are nice enough, but not very smart...none of them understands me.'
'Relax and enjoy,' counsels Bradley. 'It's like a carnival ride.'" ―Kirkus Reviews
