How do you get other pets if you are a hunter in World of Warcraft

In order to learn a new pet, you first have to find a beast you want to tame. Target it and use Beast Lore to determine if it is tameable. Then, you have to dismiss your current pet (no need to abandon it these days as it becomes one of your active but uncalled pets) and then cast Tame Beast on the creature you want to tame.

Once the channeling time is over, it has become your pet. Note that it might be useful to put a Freezing Trap in front of you to trap it while you tame it. Be sure that no one interferes with the creature, or heals you, as this might break the effect.

Once the pet is tamed, it will be hungry and unhappy. Feed it some food it likes to up its happiness.
