How to train a dog if it runs away as soon as it goes out?
You can use a longer rope to tie the traction belt, so that the dog can play freely first, and then the owner will issue a "come" command to the dog. If the dog cannot come, the owner can slowly pull the dog to his side. At this time, the dog's movements must be gentle and not rough.
When the dog returns to the owner, the owner must give the dog food or caress it, and encouragement must be sufficient. Then, gradually increase the length of the rope until you don’t need to pull the rope to issue a “come” command to the dog, and the dog can quickly return to the owner and your training will be successful.
Some dogs have a relatively long safe distance from their owners. You can hide them secretly when the dog is having fun. After a while, the dog will become very anxious if it cannot find the owner. You can make the dog anxious for a while, and the owner will issue a "come" command to the dog. The dog will quickly return to the owner and give him full encouragement. The dog will not always run so far in the future.
