combat pets are 4 hunters good luck

hunters obtain pets
frost mages obtain water element
shamans have limited time summon earth and fire element
warlocks have demons at there command
and that is all that i am aware of atm

You can get non-combat pets with any character. With Hunter, you can have your choice of animals and monsters to befriend. The other classes with combat pets are Dk's which have a ghoul and warlocks who can summon their pets. But, if u want versatility in pets, go hunter

Hunters are the only class that can have pets. Warlocks and Death Knights have minions. More specifically, Warlocks have demons and Death Knights have a ghoul.

Druids are quite versatile and are great for soloing lots of quests. Bear form can be used in a pinch if you seem to be out numbered, Cat form is good for sneaking around and delivering lots of quick attacks combined with bleed effects, Moonkin I don't know much about because I've never been one, but I hear that they can do lots of damage. You can also pop out of any form once you click on a healing spell which is nice. So you can keep yourself alive with heals, a couple being heals over time or HoTs.

If you are new to WoW, I would recommend a druid because you can heal yourself, but if you would feel more confident with a pet, then I would go with either a hunter or a warlock. You cannot choose a Death Knight yet if you are just starting out because you need to have a character that is at least level 55 on your account to "unlock" them.

Also, if you would like an in game friend or someone to ask for help, I play WoW, both Horde and Alliance. I mostly play on Boulderfist (which is more Horde dominant) and Kel'Thuzad (which is more Alliance dominant)

Hope that's helped some!

Hunters have pets. Warlocks have demons

of course not...
There are 3 types of "pets" in the game.
First one is a passive non combat "companion", a little cat or snake or pands that follows you around and doesnt relly do anything except visual "oh sooo cute" thing

Second one is a Full time Compat pet, Only hunters and Warlocks have them and its basically a part of your class it helps you in combat and you class relyes on the pet.

Third is a Summond pet, A very powerfull pet that only lasts for a short period of time and cannot be resummond for some time after the initiam summoning, AKA water elemental for a frost mage is a very powerfull pet but can only be active for 45 sec and cannot be resummoned for 3 min.

hope helped...
