Query: Too small for a Saint and other large-headed dogs

I followed the sizing chart and bought a size 10 for my 173 lb Saint Bernard (his muzzle measures 14.5"). The basket fits over his muzzle, though just barely, but the strap that goes behind his head is about 6-8" too short!! I would not recommend this muzzle for a giant breed dog, especially those that have a big square shaped head like Saints or Newfies.
