My chihuahua is a very smart dog.

[ThomCat]

She has learned to use the litter box just from watching our cats.

Often at night she wakes me up because she needs a middle of the night trip to the back yard. Last night i woke up and noticed she was doing her "I need to pee" dance. So I climbed out of bed and started getting dressed.

You could knock me over when I hear her scratching in the litter box and look to see her covering up her pee.
:wow:

If dogs can learn to use litter boxes, why don't people in cities and/or apartments ever train dogs to use them? Or, why haven't I ever heard of this before? This is Awesome if she will keep using the little box for late night needs!

The cats don't seem to mind sharing the box, by the way. We have two cats, and two boxes, and both cats seem to be using both boxes even since the dog used it. So that isn't an issue.
