How long does dire wolf enhanced damage last after it eats a corpse?

It has been a while. I rember hearing it was one of the stealth updates to the skill. But I do not remember the source. It was a couple of years ago. That being said its a moot point. The dire wolves tap out at about 1500 physical damage. Likewise as long as they have a contiuous supply of corpses. They will keep eating and refreshing. If they don’t the buff putters out pretty quickly.
