We call my dog ,Lily, Underdog because she’s always going under things. If you’re looking for her and can’t find her, there’s a good chance she’s under the table. At our old house she was always going under beds but at our new house she’s discovered much to her chagrin, that the beds are constructed in a way that make it impossible for her to get under them. She’s just too big
She’s usually driven under furniture by sounds she doesn’t like- that sound could be thunder, fireworks, music, beeping, glasses clinking together or some sound that is perceptible only to her. She has very big ears and is very sensitive to noises. One time we were walking her through the neighborhood when fireworks started going off. As there was no furniture around, she darted under a parked car.
Aside from noises, the other thing that tends to drive her under furniture is seeing an object she wants there, usually one of her toys. I said that she can’t fit under beds in our new house but she hasn’t quite accepted that fact. She still tries to get under the beds. She thrusts her head under the bed and whines and barks, hoping that if she just tries hard enough the bed will magically shift to accommodate her or she’ll magically shrink.
While Lily is too big to fit under the beds, the cat, Dr. Zeus, is not. He goes under them quite a bit, especially when he’s mad at his humans and as you can imagine this drives Lily crazy. The two of them like to play-fight and while Lily has the advantage of being bigger, Dr. Zeus has the advantage of being able to retreat under furniture. He’s taken an especial liking to the footstools in front of the sofa. I’ve taken to calling him Undercat.
