Honey badger
Because of their tough, loose skin, honey badgers are difficult to kill with dogs. Their skin is hard to get through, and its looseness allows them to twist and turn on their attackers when held. The only safe grip on a honey badger is on the back of the neck. The skin is also tough enough to resist several machete blows. The only sure way of killing them quickly is through a blow to the skull with a club or a shot to the head with a powerful rifle, as their skin is almost proof against arrows and spears.
