Help with CSS Shapes

I need help with figuring out manipulating a shape in CSS.

I’m attempting to satisfy the first challenge in #DailyCSSImages and I’m trying to make a wolf. I created an upside down triangle but I can’t figure out a way to soften the point into a chin. I tried border radius but that only did the head.
