When an adult brings food back to the puppies, located in that year’s “day care center,” the puppies will spot the adult and come running to be the first to get food. The adults tend to make the puppies follow them a bit to let the little pups catch up so they all have a chance at food. All the 18 pups born this spring by three mothers survived this summer. Many times wolf pups will starve to death because the summer can be the toughest time of the year for wolves. The prey are strongest in the summer and wolves generally only succeed in a kill one in five tries.
