I HAVE TWO BOSTON TERRIERS AND ONE IS 4 YRS OLD AND THE OTHER IS 3 YRS OLD. COULD YOU EXPLAIN TO ME WHY MY OLDER MALE BOSTON DOESN'T HAVE CRYSTAL CLEAR WHITES OF HIS EYES LIKE MY LITTLE FEMALE BOSTON DOES. IT HAS ALWAYS BEEN THIS WAY EVEN SINCE HE WAS REALLY LITTLE. I DON'T KNOW HOW TO DESCRIBE IT EXCEPT TO SAY THAT IT LOOKS LIKE THE COLOR OF HIS EYES KIND OF RUN OVER INTO THE WHITE AREA AND JUST SORT OF BLEND IN. HIS EYES GET REDDER FASTER WHEN HE PLAYS REALLY HARD AS WELL.
From what you descibe, it sounds normal. This is just the way it is and that is that. If you really want to explore the subject more I recommend a vet ophthalmologist. good luck, vetcare
