There's a saying called "dogs for once." Sometimes you don't think it's gonna help you with anything. But maybe at a critical time, they'll really help! That's when you'll be so impressed. It's so good to have them.
There's one who lives in Inner Mongolia, has a lot of cattle and a dog. The same day, the netizens discovered that one of the cattle in the family was sick, so they planned to inject it. But this cow seems to know it hurts and has been reluctant to cooperate. There's only one guy on the net. There's nothing he can do without the bull. The dog came to help!
When the dog saw the cow not cooperating, he wanted to come and help. Although the size of the two is very different, the dog is not afraid at all! Eventually, under the dog's control, the master gave the cow a shot! I have to say, the dog was useful at the moment, and no one taught him how to do it.
