The Dog Who Saved the Bees

Junior Library Guild Gold Standard selection.

When an overworked beehive inspector seeks a detection dog to protect bees from a deadly disease, she teams up with a lonely dog who needs a loving home and a purpose.

Cybil Preston needs a dog. But not just any dog. She needs a dog to help her with her work. Cybil is a beehive inspector who works to ensure the health of commercial beehives in Maryland. Hundreds of hives are shipped across the country as farmers need bees to pollinate their crops. Without the bees, there wouldn’t be foods like apples, almonds, and strawberries.

But the bees must be healthy to be shipped, and there’s a deadly disease, foulbrood, that is highly contagious. If even one infected hive left the state, entire bee populations could be wiped out. Dogs, with their ultrasensitive sense of smell, can sniff out even the tiniest scent of foulbrood in a hive. A well-trained, focused detection dog can inspect 50 hives in 10 minutes. Work that would take Cybil an entire day to do.

When Cybil meets Mack, an unruly and lonely dog, she wonders if she has found her canine colleague. Can rambunctious Mack be trained to meet this important challenge? Readers of all ages will enjoy this warmly illustrated true story of Cybil and Mack as they work to save the bees.

STARRED REVIEW - School Library Journal - The Dog Who Saved the Bees

K-Gr 3–The inspiring nonfiction account of a dog, Mack, who finds purpose in learning to use his ultrasensitive sense of smell to detect a deadly, highly contagious bee bacteria called foulbrood that spreads from infected hives to healthy ones, killing entire colonies. When Cybil, a Maryland apiary inspector, finds Mack abandoned and unloved, she decides to give her beloved bees and the lonely dog a new chance of survival. Cybil patiently trains Mack to sniff out the foulbrood while, at the same time, owner and dog develop a strong, loving bond. A rescue story for both Mack and the bees, Gibeault’s informative tale catalogs Mack’s training and growing success as it educates readers about the environmental importance of bees. Audiences familiar with the more traditional uses of trained dogs will delight in learning about Mack’s highly specialized work, especially through the warm watercolor and ink illustrations that cleverly connect his growing skills directly to the life of the bees. Love and mutual respect radiate from the text and pictures—“Cybil had found her detection dog. But Mack had found his home”—which will make readers root for both Cybil and Mack’s bond and the survival of the bees. Back matter offers further information on foulbrood and bees.VERDICT High-stakes and wholly unique, this true story highlights the environmental value of bees in addition to celebrating the bond between dog and owner. Recommended for all collections.

Bee Culture Magazine - The Dog Who Saved the Bees

This new book, The Dog Who Saved The Bees, is about Cybil starting from square one and resurrecting the Dog Inspector AFB ID Program. The book is a short fun and informative story about Cybil and her adoption of the energetic dog Mack and the time, effort and love to get Mac trained for Maryland Beekeepers. Illustrations are colorful and connecting to the story and the reader. Thanks to trainers like Major Mark Flynn who helped Cybil and Mack, Mack was certified as a Scent Detection Dog. We all know that to ID AFB requires us and or an Apiary Inspector to disassemble a beehive and look at every inch of brood comb. It takes a long time. Mack was able to use his excellent scent of smell and put his training into practice and searched more than 1,600 individual colonies in a single month! Cybil and Mack received the Customer Service Heroes Award from the Governor of Maryland. But I haven’t told you the whole story. You need to read the book and become impressed like I was with Cybil and Mack and Mack and Cybil.

Kirkus Reviews - The Dog Who Saved the Bees

Dogs can handle all sorts of jobs, but even so, Mack’s line of work is most unusual. Being chief apiary inspector for the Maryland Department of Agriculture, Cybil Preston is charged with certifying that commercial colonies of honeybees are free of the infectious disease called “foulbrood.” Visual checks are one way to do that, but because the job would go far more quickly with help from a dog trained to sniff out the malady’s distinctive smell, Mack comes into her life. This true story is partly a heartwarming tale of a lonely pooch finding a home, but, a professional animal trainer herself, Gibeault also lays out in loving, precise detail the systematic series of humane challenges and rewards that turned a rowdy, distractable dog who at first wouldn’t even sit on command into a dependable and responsive worker. A yellow Lab whose big personality shines in Hohn’s illustrations, Mack will easily win readers over as he passes each test and gets to work, then goes on with the light-skinned Cybil to earn a public service award and even enjoys a fling with media stardom. Following a final turn proudly trotting past piled-up beehives, Mack poses in backmatter snapshots using his expert sniffer and working alongside his own successor. Would-be animal trainers will find this engaging addition to the working-dog shelf of particular interest. (afterword, bibliography) (Informational picture book. 5-7)

The Horn Book - The Dog Who Saved the Bees

Gibeault’s text nicely balances details about beekeeping and dog training with plenty of action and emotional appeal. Hohn’s soft illustrations in an earth palette bring dog Mack’s lovable, if at first unruly, personality to life.
