What to Expect: Animal welfare, puppy mills, friendship, family drama, courage, and middle school life.
A powerful and poignant middle-grade novel, A Dog Named 647, written by Nancy Kay, delves into the dark world of puppy mills through the eyes of twelve-year-old Mia.
When Mia discovers a pregnant, mud-colored stray dog—whom she names 647—in a quiet meadow, she finds herself on a quest to expose the horrific, unspeakable conditions within the Pine Valley Puppies kennel, where 647 is tragically confined, and countless other dogs endure unimaginable cruelty.
As well as being a story about animal rescue, it’s also about Mia’s journey of finding her voice and learning the true meaning of courage, often with the steadfast support of her best friend, Cassie. Serious themes are interspersed with moments of humor and the warmth of friendship and empathy, offering a well-rounded reading experience.
The narrative portrays the horrific realities of puppy mills, from the unsanitary conditions and lack of care to the heartbreaking suffering of the animals. Yet, Kay’s vivid descriptions are unwaveringly impactful without being overly graphic for the intended audience—her inclusion of a compassionate veterinarian, Dr. K, and Jack Elliott, the head of the Brookfield Animal Shelter, helps provide a realistic and inspiring pathway to understanding how individuals can advocate for animal welfare, along with the helpful backmatter titled Things We Can Do.
A testament to the power of compassion and the difference one determined individual can make, young animal lovers will find A Dog Named 647 to be a compelling and important read that will likely inspire them to speak up for those who cannot speak for themselves.
