I love the way Jesse Hartland draws. The book in the photo is called Clementine in the City. It's about a big black poodle (Jesse's own) who moves to the big city. After Clementine buys a pair of the best boots in town, she has adventure after adventure. (True, that's usually what happens when you buy the best boots in town.)
Three other dog books from my shelf that I love: Martha Speaks by Susan Meddaugh, Amandina by Sergio Ruzzier, and of course Higgledy Pigglety Pop! or There Must Be More to Life by Maurice Sendak.
