It really matters how old she is as to what approach to take.
You could try putting a peepad down for her in the house to see if she'll use it. If not, you will have to get her on a schedule. They tend to go potty first thing in the morning, after they eat, after playing, after napping, and before bedtime, and whenever they come out of the crate or any confinement. If she's not confined, it may be beneficial to limit her access to all but one or two rooms.
When you start training her, take her out every two hours. I she still goes in the house, take her out every hour. Give her a treat and a ton of praise when she does go outside. Give her a command like 'Go Potty' while she's in the act... then praise her like a maniac.
If she has an accident in the house, and you didn't see it, don't say anything to her, just clean it up. (No bad eye to her either). If you catch her doing something, try to pick her up and place her outside and give the command, 'Go Potty' (or whatever you want to use, just be consistant).
Never tell her 'No' to correct a pottying problem. Yorkies are very smart. You mean no potty in this place, but she'll learn it as potty, anywhere is bad, and just be confused. Totally no reaction at all on your part to accidents. If she goes out every two hours, she shouldn't have accidents in the house. If you work... plan this training to happen on the weekend, or when you're off 2 days in a row (is best).
This is Positive Reinforcement Training, and is how most Yorkies learn best. It may take longer if she's an older dog, but eventually she'll get it. You will have to make the time commitment of a weekend or two to teach her, and then do your best during the week if you're not home all the time.
Hope this helps... |
