This will be the new sm k9 mask. I made some small edits to the original design but kept the muzzle shape and nose. raised the eye area, enlarged the cheeks and brow, enlarged the tear ducts and made the entire head a big larger.
Another thing I will be changing on all my new masks is adding more of a forehead and chin cup making it easier for customers to wear and modify the masks. I learned through my own trials that the masks require more of a base around the wearers head to prevent slipping and allow better jaw movement.
