All-in-one hunter pet macro

I would want a macro for my hunters which revives, calls or mends.
Tried this but it doesn't seem to work when pet is dead. Can anyone help please?

/cast [target=pet,dead,nocombat] revive pet
/cast [nopet] call pet
/cast mend pet

Edit: Seems it works however if pet corpse is visible, but not if you can't see it. Can this be solved?

Quick google search found this:

Code:

---

/castsequence [nopet] reset=20 Call pet, Revive pet

/cast [modifier:shift] Dismiss Pet; [target=pet, dead] Revive Pet; [pet=nodead] Mend Pet

---

I'd give you mine but I'm not at home this weekend. ;) Hope this helps.

Ugh
