Use the force Luke! (ahem, Virtues).
Anyway, you really should be using the Tamer forum. You'll find all the info you need there
UO Tamer Forum link
Have a friend peacemake, have a friend sleep it, beat it down by killing it until it has only a few hit points left or until its firebreath does minimal damage (mindblast, wither, EVs, a pet you would later stable), use invisibility spell to disrupt aggro, use confusion pots to disrupt aggro, use egg bombs to disrupt aggro, use hiding skill to disrupt aggro, use lead taming (staying a tile or two ahead, matching AI speed), make a macro in UO (use skill: Animal Taming, wait for target, last target) and spam it when you get in range (then run away if you fail), use teleport spell to get away faster if you need to on foot, use ninjitsu animal form for faster movement while taming and/or even immunity to poisons (unicorn) or faster hit point regeneration (dog/cat), use potions (heal, cure, refresh, strength, invisibility), use bushido (confidence, evasion), use mysticism's healing stone and/or cleansing winds (removes poison, heals, and lifts curses all in one shot), use magery's protection spell to make it easier to cast spells (I wouldn't recommend it, but some people love that spell), put healing/anatomy on tamer and heal yourself with bandages, use honor virtue if you somehow can't do any of the above, or
have someone else tame the dragon and help them.
