If the Yorkie refuses to go to the tray or the toilet, he should never be beaten and poked with his nose. This will only aggravate the situation, because the animal will be scared and will continue to defecate in secluded places. More importantly, if the dog has been to the toilet. If you miss this moment, it will be too late and ineffective. The best punishment for dogs is a rolled up newspaper. When the dog is "at the scene of the crime", then he may be lightly slapped on the nose or made a remark in a stern voice. You will not understand the first time, but with persistence and persistence you can achieve a positive result.
