So I did get him into a proper vet yesterday, and got several medications for him, two antibiotics and an anti-inflammatory. They also confirmed he had an ear infection, cleaned out his ear, and gave him some fluids since he was dehydrated. They said its still possible he may also have a tumor, due to the way his left eye was so bugged out.
He is at home now, and I've been giving the medications as well as food via syringe, but he has not improved. His one eye has turned a foggy blue color and I fear he may have lost vision in it. His other eye is normal colored but looks hazy, not as clear as before. He can barely move. I'm worried, but hoping for the best, that he will get well soon.
Thank you all for your advice and input.
