The pack usually don't have more than 12 wolves in it. Only one pair of wolves in the pack mate and produce pups. They are the alpha pair. They have 5 to 6 pups in late april. The entire pack helps raise the pups.
Wolves communicate with each other using the different pitches of their howl.
Wolves also use sign language. The way they position their tails, ears and lips let the other wolves know whether they are submissive, want to play or going to attack. Wolf puppies are usually born in a den that their mother has prepared. At 2 months they are already about 20 pounds and is ready to run, jump, play and explore.
