If you ever get in that situation where you are being attacked from behind on your Rhino, and you can’t turn around to attack because your constantly being pushed, just get off the Rhino and then it will turn around and easily and destroy whatever was attacking.
If you are on a pvp server(pve works as well), and you're raiding someone, try to use the rhino's charge attack. If your opponent has a rex, and you hit it with a full charge meter, it will be an instakill.
The wooly rhino is a great tame I got a 150 perfect tame and just used it in a raid and it took down 3 Rex's and with the help of another rhino we took down a giga really recommend this dino
Get a male and a female rhino breed them until you get around 500+ melee damage, with 100% imprint it almost always rages gigas with one full charged attack.
