Rowdy's third eyelid started covering his left eye about an hour ago. It was red and watery too. I gave him some benadryl and it seems to have helped some. It's not covering his eye but you can still see it. His eye is still watery and he seems to be winking. I took him to the lake yesterday to run and swim. Last year when I took him he had little red bumps all over his chest. He was allergic to something he came in contact with. Could his eye be an allergy as well? If it was an allergy wouldn't have started right away? Would it only happen in one eye? His eye isn't swollen. The only other thing I could think of is that it was poked while he and Capone were wrestling this morning.
