Are Damage Shields On Pets Neutral Damage?

[Curmudgen]

Title says it. Started a Mage. A friendly Druid gave me a DS and when two mobs engaged me one died wholly from the DS and I got no exp for that one

This got me to wondering about the change to pets where you have to do the 51% more damage thing over pet to get full experience. With the fire pet DS, if it's neutral damage do you just have to do more damage than it's nukes and melee hits only to get the full experience?
