Has your yorkie ever tried to made a fake hole in your bed and try to cover it with nothing????
Yesterday I was looking for something in between the couch pillows, I didn't find what I was looking for, but Bengi found an old piece of flossie. He grab it and took off. At night, when we were going to bed, he showed up with the flossie in his mouth. He started to walk around the bedroom, so I figured out he wanted to hide it somewhere.
He got on top on the bed and started to look for a place to put in between the covers. I kinda helped, and pushed a hole in the comforted between the footboard and the end of the mattress. He kept going around and finally put it there, and push it with his mouth, more and more (so nobody would steal it

) Then, he started to move his face like he was throwing something into it. Like he was throwing dirt on top of the hole, to cover his "treasure". Poor thing! it looked soooo funny, like a crazy dog!

That has instict written all over it!!!!
I guess that's all an apartment dog can do!
