Well our dog Liko (pronounced Lee-ko) might be going blind. He is an English Springer Spaniel and just turned 2 some time this month but the other day I noticed that his right pupil was dilated while his left wasn't. At first I just thought I saw it wrong and forgot about it. Then another day went by and I asked Shane if he had noticed it too. He figured it was probably a weird reaction to the light or something and then we dropped it. Now about a week later it is still dilated and it is barely reactive to light. After doing extensive research (which reminded me I needed to do a virus scanner on my laptop) it is either nothing, an irritation that will go away alone, or glaucoma. My poor puppy might be headed to live with a handicap the rest of his life. At least it's not one of my kids.
