My 12 yr old sweet ol boy has been feeling really bad, he is lethargic, w0n't sit, only lies on his side. won't walk, eat (only selective foods like a hotdog or a piece of chicken etc.)His bones are starting to show. He has a leaky discharge from his private and the same from his eyes (greenish), It's been a week now and he is no better. He's not throwing up and doesn't seem to be hurting just miserable (but i DON'T KNOW)We do not have the money to take to the vet and I know he is old, I just want to make sure he is not suffering. What should I do? I have been giving him 1 aspirin 2 times a day to help.
