For most hunters in world of warcraft, their choices of bets are based on what buffs they need to raid. But in my opinion, all the given pets do the same DPS, and base damage as well.
The differences between pets damage are their talents and abilities.. Hunter pets have special abilities,such as stuns and roots. But these special abilities cannot bring extra damage to monsters. Before you choose a pet for your hunter character, you should consider an important factor that every pet will do the same damage as other ferocity pet .
There are some pets featuring of cunning and ferocity. These ferocious pets have accesses to Spider's Bite pet , and give them extra 9% crit chance. However, for cunning pets, they have a handful of abilities to boost DPS. The difference between these two kinds of pets is minimal. Cunning pet is doing more DPS for MM and SV hunters, while ferocious pet is better at BM .
