Much prefer it to the box
Looks great and easier for my 6lb chihuahua to get into.
The cardboard box is great, no leaks, but the tray makes the patch more attractive.
Looks neater, beautiful!
We have a Yorkie and purchased the standard patch with black tray. Our yorkie loves it and ***** train has been easier. I do recommend the black tray or wooden box because dogs tend to chew on the cardboard. Our yorkie is 9 weeks old and I bought the black tray and wooden box . For right now we are using the black plastic since she’s so small. Perhaps latter we plan to transition into the wooden outer box. You really don’t need both.
