A leveling build, you'll want one like this:
http://www.wowhead.com/?talent=cxbh0xgRwuVoVxbRVPeople like to put points in Improved Mend Pet/Revive Pet, but I see them as wasted points.. do what you wish.
A pet.. I see plenty as fit.
Cats are generally what people choose.
Bears are close, they have more HP/armor at the expense of a little bit of DPS.
Boars are very cool because of their charge skill- it's basically Dash/Dive but also gives it a bit of a damage boost, meaning you have a smaller chance of pulling aggro from it.
Ravagers are my favorite pets at the moment, they're similar to cats, just instead of Claw they have Gore, which has a chance to do some nice damage.
I don't think you can really go wrong in picking a pet, though. Unless you pick one with caster stats(You can tell it's a caster if it has a mana bar before you tame it)
Make sure you always have the highest rank of Growl possible for your pet. It's trained at a Pet Trainer(always found near a Hunter trainer). Skills like bite/claw/gore/charge aren't trainable like Growl is, you'll have to find it in the world and tame an animal with that skill in order to learn it.
