How do you increase the amount of wolves in your pack? Sort just started this game a couple of days ago, any help would be much appreciated. :-)

You can buy other peoples wolves, or breed your own. If you breed your female, get get the pups

Ok thank you. Oh can you tell me how to make a bigger den so k can hold more wolves?

You can buy more den space at Realm > Barter > Apples. Each Den Expansion costs 20 apples and adds 5 permanent slots to your den.
