my little thief

Olive, my GSD, has developed a habit of carrying rugs away from their proper place.

This morning i was showering, and when i pulled the curtain back, both of my bathmats were gone, and were splayed on her bed.

I put her in her kennel on the days that i go to work and my fiance is not home. But most of the time she is not in it. She has a little pad inside the kennel, and sometimes she'll go in, get the pad, carry it to my bed and begin to chew on it, or just sit with it in front of her.

What is up with that?
