Since most dog owners are usually busy, they rarely take their dogs out for walks. Therefore, the dog will be very excited every time before going out, and may even become excited. In severe cases, the pet owner may be scratched by the pet dog. In fact, generally as long as the pet dogs are raised indoors, they like to go out for activities. This is due to the nature of dogs. As soon as the door is opened, the dog will want to rush out. So when pet training your dog, you need to do this: Open the door first, then close it, and issue the "wait" or "back" command at the same time. (Note: This command is best trained before the dog eats.) Use the command to stop the dog's urge to run away. If the dog is obedient, take it outside. When returning home after going out, the "wait" command is also given at the door. Wait until the dog is ready, and then give the "OK" command. At this time, you can let the pet dog enter the house. When your dog is overly excited and wants to pounce on you, you should not obey it. Put a leash on it and let it calm down before continuing. Rewards or punishments can also be added when necessary. Dogs are very smart. If you train them a few times, they will naturally understand your instructions. This can avoid injuries caused by over-excited dogs.
