If you kill it than
Sometimes it gives you some prime meats

Leave these on aggressive in your base I you have a couple of high lvls someone raiding your base will be in for a very unpleasant surprise

Usage in game:
1) tame aid- can preserve prime meat allowing you to tame carnivores with ease.
2) pack hound- I’d personally only recommend for packs of five and upward, but their ability to heal like Argents means they gain strength with every victory.
3) Pet- Their just cute.

I use mine as a pet

He’s the goodest boy

His name is Gud Boi

Worth every second of frustration too get

You can make them a meat pack wich works as a preserving bin.

Once tamed you cannot ride them but you can place saddle bags on it to act as a preserving bin and eating a dead corpse will regain its health almost instantly

Walking fridge

If you have a wandering caravan of Dino’s this can be a portable fridge, and can help in fights

Does not gather fiber. Please remove this from resource gathering.

If you’re breeding for mutations, the rejected pups make good prime meat to feed the alive ones. A little sad and barbaric but it works for me...

They be cool they act as a living preserving bin tame packs of them to easily overwhelm enemies

Dakronik's fun facts:

The hyaenodon will let you know a few minutes ahead of time that it is going to rain. It will notify you using a sort of whimper and bark.
Do with this what you will!

Little known fact, they reduce the weight of raw meat from 2 lbs per stack to 0.8 per stack.

Great things to bring with you when your gonna tame something because it can carry prime meat and the prime meat will last longer inside it's meatpack. All you have to do is cryopod it and bring it over to your soon to be tamed creature then throw it out and put the meatpack on it and just stuff with your prime meat for your tame and wait until the knocked out creature is hungry then put one prime meat out from your hyaenodon meatpack into it. And then repeat until it is tamed.

Just kill every single one in sight they give a stupid amount of XP and are easy to kill. Grab a XP boost and watch your Dinos level like never before!

Very easy to breed. Make excellent cave divers. Alpha does over 1000 dmg per bite with 800% melee and a +4 pack bonus and mate boosted and petted.

Just did the ice cave on the island with 8 of these. It was a cake walk. They took on 20+ bats at once. Hard to get them in and out the cave though.

When you ask them to follow you they tend to stay closer to your character then other Dino's making them better for caves, and they can act like a mobile fridge.

Easy to find, breed and level. King of Cave Diving. Can use golden hesperornis eggs to quickly level up petting and pack bonus make the tanky with high dps. Can easily reach 4k hp with 500% meelee. Yutyranno buff will make them extremly hard to kill, they heal themselves when eating corpses are small and get armor through their saddle one of the most reliable creatures on the ark.

Can be heard howling like a banshee at night .......... only at night
