No Roses For Harry, written by Gene Zion, illustrated by Margaret Bloy Graham, HarpersCollins, 1976.
I remember reading this book to my younger sister and being amused by it, although I was far too cool to show my amusement. Now I can laugh openly because I'm a mom.
Harry is an adorable white dog with black spots. Grandma made him a green sweater with pink roses on it for his birthday. Silly Grandma. Kudos, though, to Grandma for not getting upset when she saw what Harry did with his sweater, and even more Kudos to Grandma for giving Harry exactly the right present for Christmas.
