Make sure that you do not have your spyglass in your hand when hopping on the Equus. If you do, it will make you auto-look through it and you won't be able to put it away. You won't be able to see the feed prompt and will be kicked off. This just happened to me on a 150 Day is during x2 -_- Please upvote so our fellow survivors know!
This is supposed to help others on mobile. To feed the horse “equip” the carrot while looking at it. To see that you are looking at it a little blue and black thing will pop up. Then once its fed get close and look at the left upper corner of the screen and ride. Once it starts bucking tap the carrot in the corner of your screen. (A little side note: Keep jumping until it runs out of stamina. It becomes easier to take and more likely to not run into a Rex or something.)
The biggest butt-hope in the wilderness. If your planning to tame one;
1. Reassess your taming needs
2. Go tame something more easy, like a titanosourus
If you really want one, you’ll have to feed it, jump on its back, feed it while your on it’s back without you getting thrown off. Or it running of a cliff.
If you can successfully tame one just go one-hit KO the Overseer.
PRESS THE SAME BUTTON TO FEED AS YOU DO TO MOUNT, and feed him as soon as you mount! For me on Xbox, it's Y. Then press again all times he tries to buck you off. Lost a unicorn because I didn't know what button would feed him, I thought the mounting button would make me dismount.
I know this is about the Equus but i tamed my unicorn without mounting it. Not sire hoe different they are but i had ghille suit and crouched the entire time behind it and kept feeding it carrots. Tamed in 4 carrots with a level 35
