If your Yorkie is used to the puppy pads, this might be a comfortable option instead of going outside, especially when the weather is bad. My dog uses her
indoor dog potty when I am at work, and I walk her when I get home. Jaz is not able to wait 8 hours to relieve herself, and sometimes if I get stuck even later, I know she is comfortable.
I think for many dog owners are changing the old school thought of dogs only should "go" outside. I used to have to bring my dog to the kennel when I had to leave town on business for the evening, or find a willing neighbor to walk her. Now I can leave her food, water, chew toys, and dog toilet, and she is fine for the night, and more comfortable at home. She would not eat when I took her to the kennel.
