You need to believe that this spell will work or it's not going to. It will be a day at the most that your wolf will find you unless you don't believe. It's a spirit wolf, so it will turn invisible to anyone but you when asked. The only other reason it wouldn't work is if the wolf spirits think you're too young, which is possible but not guaranteed. I'll answer any more questions in the comments below, and I'd appreciate it if you subscribe!
