There are several ways to house break your Yorkie puppy. You can train your puppy to go outside, go on papers or pee wee pads, or to go in a litter box. We recommend you start by crate training your puppy. Dogs are den animals and actually feel secure and safe in a crate. They don't think of a crate as a "cage" but as their den and will try very hard not to soil their den. The crate can be plastic or wire. Buy the smallest size for a puppy for house training. If the crate is too large the puppy may use a corner or one end for a bathroom area. It is possible to buy a larger size and either close off the end with a divider or stuff a pillow in the end to make it smaller until crate training is over. See samples of crates here.
  A crate used correctly for house training becomes the dogs own private retreat or den. The puppy will seek out the crate when it wants to rest undisturbed or to feel safe.
  A crate's success as a housebreaking tool is simple, puppies will not soil their sleeping area if they can possibly avoid it. But remember that a puppy needs time to play and has a small bladder. Use the crate when you can't watch your puppy, but don't overuse it.
  Crates come in different styles and sizes. Choose one that will be large enough for an adult Yorkie to lie down, stand up, and turn around easily. If you plan on traveling with your Yorkie buy a plastic one with ventilation slits on all four sides.
  Put the crate in a room close to other family members to lessen the puppy's anxieties. Move the crate at night to the bedroom so the puppy will feel like a member of the family and so you can hear the puppy if it needs to go out at night.
  Remove the puppy's collar before placing it in the crate. For the first few times the puppy goes in the crate she may cry or whine. Give her a treat when you put her in the crate, close the door, then leave the room but remain close by. At the first bark, whine, or howl intervene with a sharp "NO". Your puppy should associate the reprimand with its actions and stop. It may take four or five tries, but it will eventually settle down and be quiet. Never take the puppy out before she settles down or she will think all she has to do is keep making noise until you take her out.
  Once the puppy is quiet, keep it in the crate for 30-45 minutes. If it begins to cry, take it outside to relieve itself. Once that happens, praise the puppy, give it a small treat, and take it back inside and allow it supervised free time outside the crate. If she starts chewing on something other than her toys, respond with a sharp "no", take the object away and replace with a chew toy.
  After 15-20 minutes of playtime, put the puppy back into the crate for a nap. Correct the puppy if she cries. Your puppy learns through association, so consistency should help it accept being in the crate after a few times. After about an hour, take puppy out again and repeat the process.
  Your puppy will need to eliminate directly on waking and shortly after eating or playing. Also, a very young puppy will not be able to hold its urine all night, so be prepared to take her out during the night.
  Put the puppy on her leash immediately after letting her out of the crate. Rush the puppy to the door or carry her so she can avoid an accident. Watch to be sure that she relieves herself once you are outside.
  Gradually increase the time your puppy is allowed to play out of the crate after she relieves herself outside but always supervise the puppy until she is reliable. A good way to let puppy have some play time while you are busy and don't want her to have full run of the house is to use a play pen or exercise pen. You can set it up in the kitchen or other room of your house or even attach it to your puppy's crate. See an example of an exercise pen here.
  After house training is successful you may still want to use the crate or exercise pen when you are gone or sleeping so puppy doesn't get into any trouble when you can't watch her.
