Because it loves you.
you have steak in your pockets?
It want's to be your puppy ^^
You may want to see someone. Sounds like a hallucination.
That acid you dropped is still affecting you
usually a wolf who is following you probably would be thinking of eating you? i dunno, sounds kinda scary. there was this movie 'wolfen' though where wolves were spirits and only some people could see them. a couple days ago i read a dream (here on EP) where someone was having a dream wolf over and over again. i just had a wolf in my dreams a week ago or so, i thought it was interesting. sounds to me like 'spirit animal' but i dunno. you sure it is a wolf?
You smoke too much herb there buddy
