 The consequence is that wolves put a lot of energy into producing a few pups in contrast to dogs that maximize the production of pups.This higher pup production rate enables dogs to maintain or even increase their population with a lower pup survival rate than wolves, and allows dogs a greater capacity than wolves to grow their population after a population crash or when entering a new habitat.It is proposed that these differences are an alternative breeding strategy adapted to a life of scavenging instead of hunting.
