How do I start my training my Yorkie?
Reward. Reward. Reward. Be sure to vocally praise your Yorkie when they do something good. It's best to start off training with only one commander. That way your Yorkie will grow accustomed to one voice, and that will bring less confusion. When your Yorkie comes when he is called, praise him. You may want to give him a little treat, some kind of food will work. Once he relates the treat to being obedient, he will learn.
Also, be patient. Training is not a one-time thing. You will need to put aside perhaps 30 minutes or an hour each day for a few weeks to teach your Yorkie.
When your Yorkie does something bad, do scold him.
Never hit your Yorkie, a loud clap of your hands, or make a loud noise (like using the cardboard part of a paper towel roll) will be sufficient. You can also "quarantine" your Yorkie or leave him alone in the bathroom, or put him in a high area (make sure he won't jump). Don't quarantine him for too long, perhaps 10 or 15 minutes.
