My Corgi, Dora, takes, toys, bones, balls, etc. and sticks them under the sofa, chair, china cabinet, etc. Then lays on her side and barks and scratches until someone retrieves them for her. Last night I was throwing the ball for her. She would run and get it, then bring it back and drop it. After about 10 times, she ran back and shoved it under the sofa next to me. Do all Corgi's do this or is mine just flying her freak flag? If all Corgi's do it, does anyone know why?
