What's with the puppy barking in bed?
In fact, the problem of defecation can also be well educated. Take the smell of newspapers occupying the dog's ass, put it where you need it to pee, such as the bathroom, familiarize it with it, and when it smells the tendency of urinating around, quickly take it to a fixed place to solve it. Repeat several times, and then make sure the bathroom door is always open. Keeping a dog should be patient, just like teaching a small pot friend. At first, it should be done step by step.

Dogs belong to Chordata, Vertebrate, Mammalia, Orthoptera, Carnivora, Schipoda and Canidae. Chinese is also called "dog", and dogs are distributed all over the world. Dogs, horses, cows, sheep, pigs and chickens are also called "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, and it has developed to this day. Known as "the most loyal friend of mankind", it is the pet with the highest feeding rate at present. Its life span is about ten years.
Dogs are domesticated by wolves. As early as the era of hunting and gathering, people have domesticated dogs as hunting assistants. So dogs are the earliest domesticated domestic animals. Dog bones have been unearthed in Cishan, Wu 'an, Hebei, Peiligang, Xinzheng, Henan, Hemudu, Yuyao, Zhejiang, which proves that it has a long history of domestication. The dog-shaped scorpion unearthed in Sanlihe, Jiaoxian County, Shandong Province (Figure 3-50) is vivid and lifelike, which enables us to see the morphological characteristics of domestic dogs in the Neolithic Age. The dog bones unearthed from Anbanpo site in Xi 'an, Shaanxi, have small skulls, protruding frontal bones, slightly cracked teeth and curved horizontal edge of mandible, which is quite different from the present North China Wolf, indicating that the history of human domestication of dogs is indeed very early.
