I can't have a cub and I'm level 10, why is this?

Both wolves must be level 10 and fall asleep in a den. When you wake up, the female will be pregnant. Falling asleep again will not make the puppy born! You must gain xp for a special level for pregnant wolves, (the progress bar will be pink for this special level). Once the progress bar is full, go and sleep in the den again! When you wake up, your puppy will be there!

You need enough exp for your female character and you need two level 10 partners.

You and your mate have to both be level 10 and then the female will become pregnant and will eventually give birth my female just gave birth recently and you won't believe how hungry the baby gets!

You need to have you AND your mate at lvl 10

Are both you and your partner at level 10? or just you?
