To reduce chance of killing it while trying to knock it out is by shooting with a primitive crossbow without delay until it starts to show blood then switch to a regular bow and then space shots 7 seconds apart - works every time for me no matter the level
A high level can easily take down Alpha Carno's. It's perfect for taming other animals since it can collect both berries and prime meat. It can go through the central cave and is a highly speedy mount with good carry weight. It's also cuddly.
