Here are concise, in-demand facts about dogs from reliable, science- and welfare-oriented sources:
- Dogs are a domesticated subspecies of the gray wolf, Canis lupus familiaris. They were selectively bred from wolves by humans thousands of years ago and have since become one of the most widespread and diverse mammal species kept as companions and workers.
- There are more than 400 distinct dog breeds, yet all belong to the same species. Breeds vary dramatically in size, shape, coat, and behavior, reflecting selective breeding for specific tasks, temperaments, and appearances.
- A dog’s senses are notably specialized: they have a highly developed sense of smell (often hundreds of millions of odor receptors) and acute hearing, but their color vision is limited compared with humans. These sensory adaptations support hunting, detection work, and social communication.
- Dogs have been trained and used in a wide range of roles beyond companionship, including search and rescue, police and military work, guiding and assisting people with disabilities, therapy, herding, and guarding.
- The bond between humans and dogs is ancient and profound, with dogs recognized for their capacity to read human cues, respond to human emotions, and form strong social attachments. This close human–canine relationship has shaped both dog evolution and human society.
- For health and welfare: proper nutrition, regular exercise, mental stimulation, veterinary care, and appropriate socialization are essential to a dog’s well-being. Different life stages (puppy, adult, senior) have distinct care needs, including vaccination schedules, dental care, and parasite prevention.
