What it is
Dogs (Canis lupus familiaris) are domesticated descendants of gray wolves, classified within the family Canidae. Selective breeding over thousands of years has produced hundreds of breeds with wide variation in size, coat, and temperament, suited to roles such as herding, guarding, hunting, and companionship.
Key details
Dogs are omnivores in practice and require a nutritionally complete, balanced diet, typically from commercial dog food or carefully prepared home meals. Their average lifespan is about 10 to 13 years, with smaller breeds often living longer than larger ones. They communicate through body language, vocalizations like barking, and scent marking.
Why it matters
Dogs are common companion animals in Canada and serve in service, search and rescue, policing, and assistance roles. Understanding their care, behaviour, and lifespan helps owners provide proper nutrition, training, and veterinary attention, supporting the well-being of both dogs and the communities they live in.
