A suggestion to pull this off a bit, instead of halftoning everything, only put tone where cast shadows might fall, like on the back far leg, the base/under the tail, the neck from under the cheek, the far forepaw, far ear, and base of the folded ear. Leaving some open spots makes it cleaner and less confusing!
Here's what it looks like with just the shadows
