Guild Wars 2

as the tittle says

Any level, even level one. Just find a Juvenile version of that pet out in the world, you can walk up to it and tame it. I forget what button it is, it will tell you when you get close to it.

any level, as long as its a juvenile it can be tamed

ninja’d by Akhet

And as long as your character is a ranger.

there is that too

The only other thing to mention is how to find the juvenile pet to tame. There are several in the racial capitals as well as Lion’s Arch, and many more out in the rest of the world.

The wiki will usually mention what is available in a given region (e.g., “/wiki Queensdale” in game) as well as giving some rough directions on location. Or use “/wiki Juvenile Armor Fish” (or similar) if you’re looking for a specific pet.
