I use potty pads as well
Bee is just so small that she cant hold it long, she is only 4 pounds. Yorkies have a more difficult time being "outside trained" because they are so small so their bladders are little. She is 100% potty pad trained, yes she does go outside too. But sometimes I dont think she should need to go out yet & she does, so she runs into the kitchen & goes potty on the pad. I only have one pad in my house, in the kitchen
they dont smell for us either, like a liter box smells really bad I guess(I wouldnt know I dont have a cat) but these dont, when they become full you can throw it out & change it, I get "lots" of 1000 for around 20-40 dollars on ebay. Becuase they are much more expensive at petstores, just makes sure you have enough so you never run out. I have a pile in my basement
