A scruffy, homeless dog who loves to dig unearths a pile of dinosaur bones. He then does a most un-dog-like thing and offers to share with the other dogs, resulting in a happy ending for Scruff. 
 Interesting to note: In the beginning of the book, all the different shoes on the humans match the personalities of the dogs they walk/own. I also love the illustrations on the page spread where Scruff burrows for the bones. 
 I know this would have been a favorite picture book of mine when I was a kid, right up there with Harry the Dirty Dog and No Roses for Harry. Recommend for dog lovers.
