8. Handle accidents the right way
There will be accidents. How you handle those accidents will have a huge impact on how easy or difficult the training process will be.
First, only correct your puppy if you catch him in the act. Fussing at him after you’ve found a mess does no good. Even if you bring him over and show it to him, he’ll have no idea what you’re mad about. If your puppy has an accident, accept that you weren’t watching closely enough, clean it up, and take the puppy outside.
Dogs are very sensitive to the tone of their owner’s voice. If you do catch your puppy in the act, a stern tone is enough to let him know you’re unhappy. Don’t ever physically punish your puppy.
