I'll have to check out the skills page. I'm an ex WoW player and was a Hunter on that and for all your pets you had to tame them, learn the skill, if you wanted a new pet you had to make sure the new pet could use the pet skill you just learned, etc etc. So a little unfamiliar with the pet skills on UO. Back in the day when I used to play I just gained up Taming to tame and ride new mounts and never really did anything else.
