I'm not sure if there are any cookie-cutter pet specs out there yet, but here is the build I use for my Wind Serpent, also a Cunning pet.
2/2 Cobra Reflexes (might not keep this one if it turns out to be unlike the old pet skill, which was a DPS increase)
1/3 Great Stamina (if I drop Cobra Reflexes, will be 3/3)
1/1 Boar's Speed (wasn't willing to spend the points for Dive and Mobility, but increased pet speed is a big boost to survivability)
2/2 Owl's Focus (I do tend to overload my pets on focus, this one might not be needed, not sure yet)
3/3 Spiked Collar (a no-brainer, really)
3/3 Avoidance (decreased AoE damage is really a must for raiding, since that's what will kill your pet most often)
1/1 Roar of Recovery (like an extra mana pot, only better--other talents would give more pet damage, but this is nice for the hunter)
