Does your corgi vocalize in exotic and interesting ways? Cassie, who was found at the dog pound under a sign reading "BARKS," expresses herself almost exclusively in loud yaps, which is OK because no one is around to be disturbed except me, and I find her so adorable that most of the time her barking doesn't pose much of a problem.
On the other hand, Ruby the Corgi Pup appears to be a multilingual dog. She is the most amazing little talker! She has a wide range of vocalizations, some of which are weirdly human: tones that rise with a question mark at the end, tones that sound like a little kid just told she can't have another piece of candy, tones that sound like a happy teenager celebrating some new purchase...it goes on and on.
She has quite a vocabulary, and she seems to use some of the sounds repeatedly, in a pattern that appears to have meaning of a sort.
I suppose that when she makes a sound that elicits a desired reaction from the human, she must make a connection ("this noise" = "that action from the human"). So "mmmmHMMMM" gets us out the front door and launches us into a walk; hence "mmmHMMMM" becomes the let's-go-out-this-door sound. "RUF-grrd-grrd-grrr-arrh-grrda" accompanied by anxious pacing around the kitchen means "get off your duff and give me a Doggy Treat, for hevvinsake!"
Cassie's barks are pretty homogeneous, ranging from the come-hither bark delivered to the puppy to get her back in the house (it's amazing!) to the general-conversation bark to the arrogant bark used to order the human around, with a slightly more urgent someone's-at-the-door bark. These noises are pretty consistently the same pitch, mostly differing only in volume.
But Ruby emits an ENORMOUS range of barks. Pitch varies to suit the circumstances. Volume ranges from a soft "woof" slightly more intense than the classic doggy "whuff" (i.e., "WTF is that [remotely distant] noise?") to an out-and-out ear-splitting scream. She's only engaged the the latter noise once, the other day when a drug user was using the alcove outside our back gate to shoot up.
In between the ordinary bark and the enraged shriek is a sound much like a bay: arf arf arf ARF-a-ROOOOOOOO! It's not quite baying in the sense that a hound can bay, but it certainly isn't a classic yap.
Couple of nights ago, a strange thing happened, during which Ruby exhibited a fair amount of her repertoire. Whatever was going on with the dog was weird -- I assume she had a dogmare and couldn't differentiate between real and dream events. But who knows?
Who knows what mysteries lurk in the minds of dogs?
