If I Had a Triceratops by George O'Connor

The giant-pet-for-little-kid premise is a classic by now, by O'Connor makes it entirely entertaining with his cheerful illustrations and dedicated and loving pet owner.
From poop patrol to beds to baths, this little owner has it all figured out. Readers will enjoy hearing how he will love his triceratops while watching her wreak havoc left and right. My favorite illustration comes when she gets a bath and shakes the water off, monsoon style. Even the narrator realizes that having a pet is a lot of work, but, as he says near the end of If I Had a Triceratops, "It will all be worth it when she runs out to greet me at the end of the day."
