Dogs can be punished.
Bian Xiao feels that dogs have higher intelligence, and can understand some commands and expressions of their owners. For example, when the owner is very sad, the dog will accompany the owner, will not disturb the owner, and will not do anything bad. So if you find that dogs always bite, you can punish dogs and let them know that it is very wrong to do so. And dogs can understand what their owners mean. After being punished by the owner, it will be very uncomfortable and will not be bitten again. Therefore, the owner must punish the dog and cannot condone the dog's biting behavior.
You can take the dog out for a walk and let the dog's energy vent.
Instead of educating dogs, let them vent their energy. After all, dogs are not as smart as humans and may understand what humans say. As long as the dog's energy is released, they will not bite, but rest in the nest. So you can also ride a battery car and take the dog out for a run, so that the dog can find extra energy during the running and rest at home. Moreover, the owner can also buy some dog toys for the dog and let the dog bite these toys, so that it won't bite the furniture.

It's hard to keep a dog. If you have no energy or time, then you shouldn't have a dog. After all, a dog is also a life, and you can't abandon it if you keep it.
