You dont prolly want to change into a wolf. It is achieved by bi-polarity. When food was poorer it was easyer to loose 1's nose to smell of blood. When I was a vegetarian I X-perienced transformation to an animal twice &once at precense on mother jsut back hospital after giving a birth almost went after the blood scent.
Modern day human is closer to movement to a were-gorilla. Especially hockeyplayers. &were-gorillas like bananas as do all apes.
What you could do to become closer to animals is yoga, crawling in woods (for days), fasting, pictures, observing animals, getting a cat & ofcourse the wolffur-coat &dancing till you drop.
