Mirabelle is a straight-faced black-and-white Boston Terrier with a penchant for wiggling, napping, and fire hydrants. Mr. Mueller is the bowtie-wearing owner who loves to take Mirabelle on adventures. What kind of adventures? When you're Mirabelle, everything is an adventure, from running after abouncing red ball to taking a walk in the neighbourhood to chasing a butterfly in the garden. That's because Mirabelle knows what every kids knows: it's not the activity that creates the fun - it's who you're with. A beautiful sunset, digging a hole, jumping over a puddle: it's the everyday events that are magical when you're a little kid. Irresistably charming, they're like a mash-up of Mo Willems and James Thurber and Babar, with just a bit of Mr. Magoo thrown into the mix.
