It sounds like flax seed (I figured an ointment/liquid form for the eyes, one must read carefully) may be a good ongoing treatment as a simple food additive, if the dog will eat it. Is
flax seed a
seed? Where does one purchase it - I can check Amazon to see what they offer, but it may be a grocery store item for human consumption.
I try to ruse Opt morning and night, and wonder if using it once a day and say "artivicial tears" (for humans) once a day.
