The dog (Canis lupus familiaris) is one of the most common domestic mammals. It is related to wolves and foxes, and has lived with humans for thousands of years as hunting companion, guard animal, object of scorn or adoration, and best friend.
The relationship between dogs and humans is unique. It is the oldest symbiotic relationship between two animals on earth and it continues to thrive today in many parts of the world.
In the United States and much of Europe, dogs are highly valued for their loyalty, friendship, and protection. They also work as service animals, in law enforcement and the military, as sled dogs on the snow, and as effective hunters and trackers. In some developing countries and in some cultures, however, the relationship between human and dog is more distant.
Dogs have evolved into more than 400 distinct breeds that fulfill distinct societal needs. Through the earliest forms of genetic engineering, dog breeders have created dogs that have specific characteristics that appeal to owners and serve their purposes.
The behavior of a dog is a complex matter that is affected by both internal and external stimuli. To understand a dog’s behavior, you must first have a thorough knowledge of the physical, emotional and social aspects of the animal. In addition, you should know how a dog thinks and how it reacts to certain situations. This will help you determine how to train and interact with your pet.
