Puppies can grow beards. The age of a dog depends on its teeth, not its beard. According to normal growth, its beard should grow at the same time according to the growth ratio of its body. If it becomes shorter, it may be artificial, or it may be broken when playing. There are many nerves at the root of a dog's beard, and whatever touches the beard will cause a sensitive reaction. Dogs belong to Chordata, Vertebrate, Mammalia, Orthoptera, Carnivora, Schipoda and Canidae. Dogs, also called dogs in Chinese, are distributed all over the world. Dogs, horses, cows, sheep, pigs and chickens are also called traditional six animals. Some scientists believe that dogs were domesticated by early humans from gray wolves. The domestication time was from 40,000 years ago to 1.5 million years ago. They are called the most loyal friends of human beings and the pets with the highest reproductive rate. Their life span is about 12 ~ 18 years.
