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

I use mine as a pet

He’s the goodest boy

His name is Gud Boi

Worth every second of frustration too get

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.

Not sure how well this would work but I’m trying to give an actual use for this dino unlike other people who basically just say shoot it in the head for prime meat. Ok so here’s my idea, what if you made a organic polymer auto farm with penguins and hyeanodons with meatpack saddles? Basically you make a enclosed area and have a bunch of penguins breeding and a couple of hyeanodons with meatpack saddles on aggressive to kill the penguin’s off spring and yes sometimes they won’t harvest the body but they should get most of them especially if you make the enclosed area really small. The meatpack saddles will keep the organic polymer from spoiling according to online sources, the meatpack saddles increases the spoil timer of all consumables which organic polymer is. This is based off of Syntac’s element dust farm go check it out if you want a better idea of what I’m talking about. I’m gonna try it out myself.

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!

They only refrigerate meat so don't expect to refrigerate eggs, biotoxin and all that good stuff.

These puppers can literally climb walls. Had to make my breeding pet 4 high so they 50% of the time wouldn’t jump out

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

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

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 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!

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...

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.

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

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.
