Query: Heart-wrenching

Narrated by a good-natured dog named Squirrel, this heart-wrenching book describes her life after she is abandoned and separated from her family while only a puppy.Squirrel encounters many obstacles as she struggles to survive. This is not an easy read--many of the horrors faced by Squirrel are all too real.I read this book right after adopting a pair of kittens from an animal shelter. Having just seen how many abused and abandonded animals were living at the shelter made me even more aware of how hard life can be for a stray animal.Please spay or neuter your pets and support your local no-kill shelter!
