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.

A playful yet scientifically precise exploration of a dog's five senses that will help middle grade readers better appreciate the canine point of view (for ages 8-12) Did you know that dogs have millions more olfactory receptors than humans and that their noses are built to reserve some air that they breathe in just for smelling? So why the butt sniffing? Actually, dogs discern a lot of information about another dog from a whiff of that region, including the dog's health and eating habits. In five chapters that explore each of a dog's senses, and an additional chapter that questions whether dogs might have senses that people don't, this middle-grade nonfiction book explains canine senses from both evolutionary and scientific perspectives. Sidebars offer additional information throughout the text, including hands-on activities that let readers experience a dog's sensory abilities for themselves. Written with an approachable tone and loaded with fascinating facts, Making Sense of Dog Senses presents readers with both curious and practical insights into their canine pals' behavior.
