pack members will look after offspring for the alpha male & female while they are out hunting, but also seen them turn on injured pack members so i'm to sure about that.
Those Dhole packs have killed tigers & leopards and they are about the size of a small collie.
African wild dogs i think have the higher success rate in all the african predators when it comes to hunting they are also known to eat prey while its still alive.
i am farely sure the wild dogs have the best success rate of all, i think its 75% success.
