We have a 12 year old boxer with a history of tumors. He's been acting very strange today and seems to have something going on with his eyes. It's almost as though a film has formed halfway across his eye from the inner corner. It also appears that his iris' are 'leaking' across the rest of his eyes - almost no white showing. I know they can't leak but it was the only way I could think to describe it. He's on a antibiotic, Baytril, for a bladder infection. His mood is very lethargic and he seems to hold his head low. Could you please advise if these symptoms indicate any serious issues we need to address? Thanks for your assistance.
