Presentation
The dog is a domesticated carnivorous mammal that has been tamed for several millennia, descended from the gray wolf. It was one of the first animals domesticated by humans, alongside livestock. Today, there are hundreds of breeds displaying great morphological and behavioral diversity.
The dog has a robust body, four legs, a well-developed head with a prominent muzzle, and ears that are typically mobile. Its coat varies in color, length, and texture depending on the breed. It possesses excellent olfaction and good vision adapted to detecting movement.

Indicative values: they vary by subspecies, sex and region.
Habitat and distribution
The domestic dog adapts to a wide variety of environments: urban areas, farms, grasslands, and rural zones. It can live in houses, apartments, or outdoors, depending on the breed and the conditions provided.
CURRENT RANGE
The domestic dog is present on all continents and in almost every country in the world, in both urban and rural areas. Its distribution follows that of humans, as it depends entirely on human support for its survival.
Behaviour
The dog is a social and gregarious animal that naturally lives in packs. It is strongly attached to its owners and other members of its group, and develops lasting emotional bonds. Dogs are playful, curious, and may be aggressive or fearful depending on their training and socialization.
Reproduction
Dogs reach sexual maturity between 6 and 12 months depending on the breed. Females have seasonal reproductive cycles with heat occurring typically twice a year. Gestation lasts approximately 63 days, and females give birth to litters of 3 to 8 puppies on average.
Peculiarities
Dogs possess exceptional hearing, capable of detecting sounds at frequencies far beyond human perception. Their sense of smell is up to 100,000 times more sensitive than humans, making them invaluable for detection tasks. They also use complex vocal communication (barking, growling, howling) and body language.
Threats and conservation
As a domesticated animal, the dog is not threatened with extinction. However, populations of stray or feral dogs may create localized health and ecological concerns.
Numbers and trends vary across sources and regions. See the IUCN assessment for the latest reference data.
