How to get a god wolf on mobile: tame a few wolves from the yeti cave, find the wolf with the best hp, melee, stamina, and maybe weight. Breed a lot until you get all of the best stats combined onto a single offspring. Imprint it and level it up by killing yeti in the yeti cave (they give a lot of xp). I have an imprinted wolf (lvl 465 on normal difficulty) with 10K health 1500% melee and it does more damage than my Rex with 900% melee.
Direwolves are easily my favorite tame on the island, they are extremely good battle creatures especially in packs. Breeding and imprinting (which I did) as well as leveling them up means you can take on nearly everything. It’s extreme mobility and small size means you can use it for most caves, as well as collecting tons of chitin and meat along the way. This is a 9/10 tame for me, due to its relatively easy taming process (bola then tranq) and its extremely versatile usage.
Getting a TLC patch in March 2018 to add howl that will initiate the pack bonus for 5 minutes, will be able to sniff out players or creatures with less than 50% health, and will be able to detect explorer notes.
Vicious and lightning fast, the Dire Wolf is a great all-around mount for adventuring and attacking. I highly recommended to bring packs of Dire Wolves for any hostile situation. Whether it be kill Alphas, or raid bases, it's size, agility, and damage make for a deadly beast.
