Bob Temple Dogs

Bob rolled his eyelights in the skull's empty sockets. "Brother. You're keeping her cloistered and working me like a dog, too. That's not fair. "
I started getting out the stuff I'd need to fire up Little Chicago. "Dog, right. Something odd happened tonight. " I told Bob about Mouse and his barking. "What do you know about Temple Dogs?"
"More than you," Bob said. "But not much. Most of what I got is collected hearsay and folklore. "
"Any of it likely true?"
"A bit," he said. "There are a few points of confluence where multiple sources agree. "
"Hit me. "
"Well, they're not entirely mortal," Bob said. "They're the scions of a celestial being called a Foo Dog and a mortal canine. They're very intelligent, very loyal, tough, and can seriously kick ass if they need to do it. But mostly, they're sentinels. They keep an eye out for dark spirits or dark energy, guard the people or places they're supposed to guard, and alert others to the presence of danger. "
"Explains why Ancient Mai made those Temple Dog statues to assist the Wardens in maintaining security, I suppose. " I got out a short-handled duster made of a rowan wand and a bundle of owl feathers, and began to carefully clean the dust from the model city. "What about the barking thing?"
"Their bark has some kind of spiritual power," Bob said. "A lot of stories say that they can make themselves be heard from fifty or sixty miles away. It isn't just a physical thing, either. It carries over into the Nevernever, and can be heard clearly by noncorporeal entities. It startles them, drives most of them away - and if any of them stick around, Mouse could take his teeth to them, even though they're spirits. I figure that this alarm-clock bark he did was a part of that protective power, alerting others to danger. "
I grunted. "Superdog. "
"But not bulletproof. They can be killed just like anything else. "
There was a thought. I wondered if I could find someone to make Mouse a Kevlar vest. "Okay, Bob," I said. "Get it fired up and give it a once-over. "
