If it were me, I'd not only examine the eye very well, but examine ANd x-ray the skull for an abcessed tooth or another hidden problem.
A second veterinary opinion is now called for. Seek out a hospital with specialists and especially an ophthalmologist.
The re appearance of the problem does sound like an infection or foreign object and that will need to be found and treated properly or you will continue to see this - and potentially get worse.
thanks..i took him again last night to the emergency clinic about an hour away cause i couldnt get a vet anywhere near me to look at him after hours..they found out that its his lens moving around inside the eye with the careract. itll need surgery to remove the lens and stop the pain. im seeing an ophthalmologist at noon tomorrow then hopefully surgery asap to fix my puppy thanks!
I agree - make sure the eye is thoroughly evaluated. My dog developed "Horner's syndrome" (like Bells Palsy) at the age of 9 and it resolved on it's own. However, more serious problems like a tooth root infection, severe dental disease, a neurologic problem would be causing it. I'd have him evaluated by a place that has a neurologist or ophthalmologist if your vet isn't able to find anything else - he may need some advanced testing! Good luck and keep us posted!
