You don't need to do any quest to enter moonshade desert! O_O
Not sure if you're serious or not, but anyway you don't need to do those quest to enter moonshade desert. All you have to do is purchase a chrono key from the messenger of time npc. That npc is located on top of the platform next to the bounty hunter npc. Once you got your key, talk to the npc again and travel back. Talk to the messenger time npc in chrono world and select moonshade desert. Wait a few moments. Talk to the npc again and you're there. The mob you want to tame is the mob needed for chrono leafs to get 130 gear.
then HOW HOW I do that tell me plz:'(P.S. don't wonder if I ignore any postsgoing to leave in like 10 minutes and won't be home till late ;*asdksjnfkdfgdsfbndf
I know it's not exactly the same, but the Cerberus Pup is pretty similar to that mob and you can get it from the Pets/Mounts NPC. <.<
There are tameable Mastiffs out there as well:http://www.pwdatabase.com/pwi/mob/1539http://www.pwdatabase.com/pwi/mob/1541
