[Maximo]

Welcome to Yorkie Talk. Being so young and small, I would limit her freedom in your home to a smaller area with one pad.

Too many pads and places to go might cause a little confusion that anywhere in the house is okay.

Limiting her freedom to a smaller area also makes it easier to supervise her so that you can praise and reward when she does go on the pad. My boys are 7 years old and we still praise for pad use.

Is she maybe trying to hide her poops? Some dogs are shy and try to hide it, or they just don't like it. Having the poop picked and disposed of as quickly as possible is important to my Yorkies.

One other possible reason: when Max was a puppy, he wanted a fresh pad to poop. Try keeping the pad fresh and see if that makes a difference. Wasteful, but whatever helps them to train.
