Edward Jesse explores the character, sensibilities, and intellectual faculties of dogs, positioning them as the most faithful and devoted companions of man. The author argues that a dog's deep attachment is not purely instinctive, but develops through close association and kindness, setting them apart from wild canids like wolves and foxes.
The volume gathers numerous authenticated anecdotes from various breeds, including Newfoundlands, collies, terriers, and deer-hounds. These stories demonstrate extraordinary feats of memory, calculation, mourning for lost masters, and the ability to understand human speech and emotion. Many accounts highlight dogs acting as guardians of property and saviors of human life in perilous situations.
A significant portion is devoted to the history and traits of the extinct Irish wolf-dog, comparing its form and courage with the Highland deer-hound. The text also examines the distinct senses of dogs, particularly their acute sense of smell and their remarkable capacity to find their homes across vast distances without guidance.
The narrative emphasizes the ethical duty of treating animals with kindness, noting that a dog's disposition is often a reflection of its master's treatment. Through detailed observations of working dogs, house pets, and historical accounts, the author builds a comprehensive portrait of canine psychology. The text concludes with reflections on the enduring devotion of these animals, suggesting that their unwavering loyalty outlasts that of many human friendships.
