"Hello? Hey! Pay attention! In your pack. The dog. I swear, you heroes aren't particularly quick on the uptake.... Good. Got your attention. I'm Barbas, the Hound of Clavicus Vile. Not that I've always been a hound, or always been called Barbas. I've also been a Redguard. For a while I was a scamp, making deals with Orcs. But, for now, I am His Hound, and I serve the Lord Clavicus. A word of advice here. You've made a bad deal. This Umbra -- bad business. Things always end badly where that one's concerned. Clavicus has always been a little blind to that. And it'll end badly this time, too. So, just leave things be. Walk away. It's your best bet, really."
The Statuette of a Dog, otherwise known as Barbas, will travel into the Hero's knapsack and disappear from the shrine after they speak to Clavicus Vile. He will repeatedly speak and attempt to convince them that battling the Umbra is a bad idea. Barbas will respond accordingly depending on each option taken during the quest. Once it is finished, the statuette will return to its original place on the shrine.
