Need help patterning a mask!

Hello All! I'm bumping up against some issues with making a neoprene dog mask (note the NSFW flair). I've been trying to reverse-engineer a pattern from images of the type of masks I like, but I have found that the pattern actually overlaps itself. I'm not too sure how to reconcile this when I make the mask and need to cut out fabric... Does anyone have any tips? And I apologize if this is too risque, feel free to delete if not allowed. Pics included of what I hope to achieve and what I have now!
