Senses such as sight, hearing and smell thrive: Dogs have large eyes, erect ears and a sensitive nose, so they can successfully track prey, whether alone or in swarms. All dogs except the South American bush dog have long legs that are adapted to running fast when hunting prey. Dogs are “tip to toe” and have characteristic feet, five toes on the forefoot and four on the back. Sometimes, dogs have five toes on their hind feet (the fifth nail is called hypotenuse). The jackal has a long tail, thick fur, is usually the same color and does not have striped spots.
The average gestation period of a dog is 60 to 62 days, possibly earlier or as long as 65 days. At first birth, puppies do not have teeth, but only after 4 weeks of age can have 28 teeth. Like all mammals, a mother breastfeeds and cares for the young for several months after the baby is born, and with the help of other family members, the mother will now so aggressive. The full jaws of this mammal are 42.
