I think Seby has become the official Poop Patrol voice.
Seby has a very distinctive and clear method for letting me know he needs to go outside. He will first stand at the door and stare at me. If I don't notice him he will issue a soft woof followed by a tight circle, pivoting on his haunches. If I still don't listen, he will continue to woof softly, followed by a slightly louder growl. Once I look at him he will proceed to show off his BBall skills and jump on the door - reaching the height of the door handle.
So it's pretty clear when Seby needs out. My other dog, Glory, and my roommate's dog Tippy, are much less vocal. They'll wait all day. But as soon as I ask "do you want to go outside?", they're both right at the door, tails wagging.
So when I'm home, I tend to get focused and don't let the dogs out every five minutes as my roommate is wont to do. During the last week, there have been at least two occasions when Seby barked to go outside, I let all three out, and he proceeds to just stand in the sun and sniff the air. The other two will take care of their apparently urgent business while Seby gets a tan.
I'm not exactly sure how dog communication works, but I think Tippy and Glory each promised Seby extra cookies if he would speak up and get that two-legged person to open the door.
