Females will throw up the food she just ate to feed the pups. They may have 6 to 8 pups in a litter. Pups are born in the spring. When the baby is born it's blind and deaf. The wolf has developed the capacity to survive in any climate.
Wolves are very intelligent creatures.
Wolves have a narrower chest than the dog. They're legs are considerably longer than a dog. The wolf does not chew its food. It tears off a piece of meat then swallows it whole. The strong jaws of the wolf allow it to break the bones of its prey.
