As the owners of dogs are usually busy, they seldom take their dogs out for a walk. As a result, every time before going out, the dog will be very excited, and even have a degree of excitement, which will seriously lead to the pet owner being scratched by the pet dog.  In fact, as long as the pet dogs are kept indoors, they like to go out. This is the nature of dogs. As soon as the door is opened, the dog will want to rush out. So when pet training a dog, you need to do this:  Open the door first, then close it, and issue a wait or back command. (Note: This command is best trained before the dog eats.) Use the command to stop the dog's urge to run away. If your dog is obedient, take him outside. When returning home after going out, he also issued a waiting order at the door. When the dog is ready, and then give the OK command, you can let the dog into the house at this time.  When the dog is about to pounce because of overexcitement, do not obey it. Put a leash on it and let it quiet down before moving on to the next step. Rewards or punishments can also be added when needed. Dogs are very smart, train it a few times, and it will naturally understand your instructions. It can avoid the injury caused by the dog's excessive excitement.
