We have a George Foreman Grill in the kitchen, and as those of you who have use it know, it makes a high pitched beeping when the grill time is up. Whenever my cocker spaniel Lady hears this beeping, she immediately jumps up and starts running EVERYWHERE around the house like a nutcase, up and down stairs, barking at random things and sticking her head in every corner.
She does the same thing when I plug in my digital camera and it beeps. I did it just now and she started running in circles in my room, super alert and growling.
Another queer thing she does involves the mail slot. I think she associates the squeak of the mail slot in the front door with the mailman, because even if I'M standing on the other side of the screen door, or even on the same side as Lady, and I pick up the mail flap and let it slam, she goes crazy and barks her head off until she feels she's done. No one strange is there - it's only the sound, which confuses me a bit. Is she stupid, or just self-conditioned? And if so, why wouldn't she notice no one strange is there by the lack of a new smell?
Any ideas as to why she does these things? Particularly to the beeping? I can understand reacting to high pitched noises, but the beeping is no different from a quiet smoke detector, which is nowhere near the superhuman pitch that annoys dogs.
Can someone please explain this? It's been eating at my curiosity for months, and no one can quite give me a concrete answer I'm comfortable with. Thanks.
