Guild Wars 2

I see some people running around with animals is there a way to get one or is it for a certain class.

The Ranger class has an animal pet.

Any class can get a combat pet temporarily with an ogre pet whistle. Fire elemental powder is similar, but gives you an ember, not an animal.

If you just want something for fun, the pirate outfit can summon a bird, and there are loads of minipets that are animals.
