All wolves age at the same rate as real life, except for pups. Puppies will age faster just so rp doesn't get boringly filled with pups only squeaking for a month.
The pups will be born blind and deaf
After 5 days rp, the pups will be able to see and hear
At 8 days the pups will begin walking around
At 12 days the pups can start trying to talk
After 16 days the pups will wander out of the den and start eating meat
At 25 days they will no longer need milk and will finish learning how to talk
From then onwards they will slowly become more independent and act like the other wolves.
Once the pups reach this last stage they will age like all the other wolves in the pack.
They will be classified as adults when they are one and a half years old, but can't have a mate until they are two.
