I gave Antimonic(the warlock) the gear, spec and strat to get this done.  To get it so high you need BoK on you and your pet, Fort on you and your pet, MotW on you and your pet, etc.  You want to get anything with high stamina on it.  Anti has 3 greens in legs, bracers, shoulders.  Green legs like 129 stam(plus enchant), shoulders is like 140ish(plus pvp enchant), bracers is like 90ish(plus 40 stam enchant).  This is all a guess and don't remember exactly but those three pieces were the highest stam pieces with stam we could find.  He is also JC and has the stam trinket, he has a full polar resist set gemmed with stam, he has the 111 stam tanking trinket, he has a tanking ring(84stam), he has the undeath carrier(old feral tanking weapon+150ish stam).  Don't forget that stam is what gives your pet more stamina, not health.  We start him on the island walking straight to Sartharion(small island) and MD to him, we then have the warlock standing on the standard safe spot and tell the pet to follow then stay, the warlock will have enough hp to take a few cleaves and breathes.  The voidwalker is healed from a healer and the warlock helps dps, when the second drake is down and beyond the only thing the warlock is doing is health funneling the pet.  Don't forget to get the voidwalker glyph which is +20% stam.
