The Bull Terrier is the only AKC recognized breed to have triangle shaped eyes (from the breed standard: Eyes: Should be well sunken and as dark as possible, with a piercing glint and they should be small, triangular and obliquely placed). 

Triangle shape aside, how many standards also call for a “piercing glint?” We’re asking Bull Terrier owners to share their “piercing glint” pictures, but also answer the question: Is a “piecring glint” the same as a “stink eye?”
