easiest way to lvl pets

what is the easiest way to lvl pets when you are allready lvl 20?

go fight monsters 1-5 level's higher than your pet's level. Pets get the xp for the kill even if you don't get any xp for them.

ie if your pet is levl 5 and your level 20 and go fight a level 5 critter, you get 0 xp while your pet will get 100 xp.

Pets also get xp from missions & quests.. so if you have those still to do.. you could do them as well.

When I got my dune lizard, I grabbed Alesia and went out into the desert and trapped minotaurs and griffons. Levelled him to 20 in about a day.
