This book takes place in around the 1940's (my guess) in the home of a sharecropper family. The family's father and his faithful dog frequently go out to hunt for food because times are tough. Though a plot twist, the two are separated for years, but reunited. For my son, this was "a dog book." For me, this was a story of love and faithfulness much like Where the Red Fern Grows. I highly, highly recommend this book.
Spoiler alert: I made the mistake of reading this book to my son. I was sobbing so hard at the end (he started tearing, too) that I had to have him finish up the chapter. I was somewhat prepared for the end, but it was much more beautiful in a tragic way than I anticipated.
