Although the dog is dirty in the house, please do not beat the dog easily no matter what. If it was discovered at that time, you can scold the dog with a stern voice.
If it has happened for a long time, please do not scold it, because at this time the puppy doesn't know why you scolded it, so he can only run under the bed and hide with greater fear. Remove the puppy's excrement and odor as soon as possible, and do not let the puppy get used to continuing to defecate in this place.
Tips: However, there are very few dogs who deliberately or treat urination and defecation as a pleasure. In this case, the dog owner can take a water gun and fill it with water and punish the dog for water. It has good results for some dogs that have been taught repeatedly.
