No saddle needed.

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.

They can sniiff out hidden animal and also can sniiff out explorer nots and artifact

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.

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.

Very important early tame although it may be difficult, it doesn't require a saddle and it gathers lots of hide which is difficult to get early in game

You can put a cloth hat on them and they can be pirate dogs

I’m on mobile, and I find it hilarious to own wolfs and very practical for one reason : while they have no saddles… you can put YOUR hats on them !! Which means you can recicle your old équipement on them, and as your equipement can have quite high values… well, more tanky wolves for the win !

They can also use your hat skins, which means you can have cool looking wolfs with rex skull helmets, smart one with the nerdy glasses… or even creepy ones with the clown mask.

Only caveat is the hats still have their durability… so be careful !

12 good ones = death to all the Server

With no saddle, your wolf will have no means of armor. This means that you're way more prone to damage, so upgrading health is imperative if you want a Dire Wolf that is viable in combat.
