I have a yorkie that is 1 1/2 years old. She is trained to go potty outside but hates the bad weather snow,rain and tall grass. We live on a lot with some woods and so I am so worried about coyotes and other animals. I take her out on a leash but she hates to be on a leash. I was thinking about the litter box training?? Has anyone every tried this with a dog already outdoor trained. I don't want to make this worse... Just better. But I am thinking that when winter comes it is going to be terrible because she just stands there and won't go potty it the weather and grass is just not perfect

Any suggestions???
