Bella has started burrying her food..and not in the ground obviously, because we have tiles lol, but she´ll take her kibble, push it into the folds of clothes, sheets, covers etc, and then with her nose, she "burries" it

What´s that all about?? Does anyone elses yorkie do that?
Also, their (Bella & Milos) food and water bowl is on a mat, and Bella will also try to cover the food with the mat underneath it.She pushes it up and over with her nose.
Why would she do that? Is she trying to tell me she doesnt like the food? Is she "saving" it for later? I have no idea what to make of this at all
