Grey wolves reproduce sexually with their mate fertilization is internal and pups are born deaf and blind but alive none-the-less. They will only have about one litter per year consisting of 1-14 pups, on average being about 4-6. Sexual maturity is reached within 2 to 3 years for both male and females. After Two months pups will follow other wolves to the hunt all the while watching and learning. After 8 months the young wolves are large enough to join the hunt, and will continue until they die. The average life of wolves is 6 to 8 years but ones in captivity live almost twice as long. This is mostly due to the fact that there is a high mortality rate for pups in the wild, Because pups are highly sensitve to hunger and disease.
