A mammal of the carnivora family, Canidae. It is the oldest domesticated animal, and several species existed in the late Paleolithic period. Its ancestors are said to be similar to dingoes and pariah dogs that live in tropical Asia from North Africa, and in some areas, it seems that they were crossbred with wolves. Many have a keen sense of smell and follow the scent of their prey to find it, but there are also breeds that hunt by sight. Their body structure is suitable for running long distances and they have strong endurance. They are gregarious and omnivorous, but they mainly feed on animal matter. In most breeds, the gestation period is 63 days, and the young reach sexual maturity at 6 to 9 months, and become old at 12 years old. They sometimes live to be 20 years old. They are intelligent and obedient. There are many breeds, with more than 400 varieties. They come in a variety of sizes, shapes, hair lengths, and colors. The smallest Chihuahua weighs less than 1 kg and stands 13 cm tall at the shoulder, while the St. Bernard weighs 80 to 90 kg and stands 70 cm tall at the shoulder. The categorization by purpose is as follows (shoulder height in parentheses, in cm).
