Pet
From SWG Wiki
A pet is a creature that a player can summon or train. There are four diffrent types of pets currently in the game. The most common are droids and beasts. The other two are familiar pets (48-month reward) and faction pets (no longer obtainable).
[edit] Droids
Droids can be used for many diffrent things in the game. They can be used to assist you in combat, harvest creature resources, advertise for you, provide a private crafting station, and many other things. For more information on the moduals and what they do visit Droid crafting and for more information on the diffrent models and how they came to be visit Droids.
[edit] Beasts
With the Introduction of the Beast Master Expertise you can now once again own and use a pet in combat. Beasts are almost always stronger then Droids of the same level, and they can reach level 90. Pets can never be higher than their Master, and you can't trade pets once they are hatched from their Eggs. For more information on the Expertise, and how to make your pet you should visit Beast Master.
[edit] Familiar pets
Recently introduced as the 48 month Veteran reward, these little pets can be called, and they will follow you around. They cannot be targeted so they won't mess up targeting. They buff you with a buff for as long as they are called, and within 120 meters of you. There are currently only three of them. These are the only Pets that can be called while you have a Beast or Droid Called.
