Lvl 1-10 dodo use your fist to knock it out. Take your time since they are slow walkers. If the dos is a high lvl then use 1 tranc arrow, if that guy is a rebel then use a punch after that dart and show him who is boss. After have a narcotic just I case and a stack of mejo (purple berries) then while waiting think of a good name like dodolerious and take that fella home. Dodo tend to have low health even at high health so protect it while walking back to base, if you have an flying Dino, pick him up and drop him close to base. Good luck everyone!
On Mobile: Found lvl 290 dodo, but saved before i tamed. when re-entering game i noticed health was higher!?! So now i save-restore over and over, got over 480 health before taming, over 600 after the tame! May work with other creatures, haven't tried yet.
if u are new to ark then yes u can tame one or two but don't let ot get tooo much. i know they are cute but that's it. they are not helpful and u need to take care of them. i had so much of them and it broke my heart to kill them because i couldn't tame more dinosaurs
