I don't know. He might have hidden it. My last little chihuahua had a little stuffed chicken and I had been hugging on it and carrying on with it and she was jealous. I couldn't find the darn thing until Christmas morning - about a month - when the presents were opened. She had taken it and slung it over all of the boxes back into the corner. There was no way she could walk back there or over the stuff. She had to have thrown it. I never, ever teased her with that chicken again...
