Oh alright. What a relief! I was worried it was a fluff spell!
Well then, I would suggest a picture, preferrably a drawing you have done yourself as a centerpiece. Concentrating on all the aspects of the wolf while drawing it will empower it. You don't need blood. A husky would be closest to a wolf if you want a little fur. They are very close to the wolf family, some are even half wolf.
Another suggestion would be to do it on a full moon, and perhaps get some sounds of wolves howling to really draw the wolf spirit to you, maybe do a little howling yourself to bring yourself closer to it!
Wear a wolf in jewelry or draw one on a smooth rock. You can also purchase totem rocks that already have them neatly engraved with the image of a wolf. This way you can carry wolf medicine with you.
Sounds exciting! Good luck. =)
