I'm surprised more people haven't tested these little guys. Last time I played was in 2018 and at that time I could take 8 breed doggies with a yuti and I could take out gigas with them.. the meat pack I had was only journeyman too.. never got around to trying them on bosses. Underestimated tame.
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.
Hands down one of if not the best hunting dog in ark. Cheap to armor, pack bonus, heals when harvesting corpses, and most importantly they are treated as man sized for Dino colishion so even raptors don’t get stuck on them. High lvl pack can down deathworms and alpha Rex BUT require a anchor or the Rex will spin and do massive trample damage.
When Hyaenodon bite the killed creature body，they will recover large HP.
Attention：If a team of Hyaenodon kill a creature，the Hyaenodons that first bite the body at same time will be healing，others will not.
When killing alphas bring this on your argie or quetz and put it faraway in a safe place. Then when you kill the alpha put all the prime meat into the hyeanodon and go home with it so you have prime meat than hasn’t spoiled
