To be honest, I don't really expect pet heals....for the most part I can watch my own and throw out a Mend Pet if needed.

If, however, something critical happens and my pet's near death, I wouldn't mind a HoT thrown on him. A pet's a significant part of my DPS, so by losing him the group loses overall DPS.

Obviously a pet is lower priority than a group member, but if everything else is going fine, and you're still good on mana, some healing attention on a pet is wonderful. :)

As a resto druid, I have pet bars up in addition to the players because as a former hunter, I do realize the value of the pets. Plus, it seems that the pet's owners don't have the time to heal their pets in battle so if everyone is ok, I shoot some HoTs on the pets. I hate seeing pet corpses... it's just too sad...

I never expect heals from the healer but I always am very happy with any healer who spends a little of his or her mana dropping the occasional heal on my wolfie. If you have the time and resources it won't hurt, y'know?

However I give all healers my full blessing to completely ignore any hunter who demands heals for his pet. Hunters have Mend Pet, which is more thanI can say for my poor mage and her water elemental. Use it. If I notice the healer doesn't have time to heal my pet when I'm running with my hunter, I drop mend pet. That's all.
