I posted on here not too long ago about my 3 year old male squirrel named Augustus. He has been having some concerning symptoms. Sneezing, watery eyes, runny nose, and flicking his head. He seems to also rub his face/nose on his blankets and his cage bars. This evening I noticed that he is having trouble when he is drinking water and was gagging on it. Since my boyfriend and I live in Oregon we do not have access to a vet that will see him.
I was given previous advice to give him Echinacea drops in his water to boost him immune system. I have been giving him these going on two weeks now. He seemed to stop the sneezing for a few days but then he was back to doing it again. He is eating and drinking normally, (besides the gagging when drinking water), and playing with his siblings. His siblings do not present any of the same symptoms as he does. I also sent pictures to someone who works at the Squirrel Refuge in Vancouver and they said his eye looks normal and doesn't appear to show signs of Odontoma. I have checked his teeth and they don't seem to be very long. He chews on Antler's occasionally. I have not thoroughly checked out his ears but I am also not really sure what I should be looking for?

I was also told to get Fish Cipro 500 mg, which I have. I am curious if I should start him on antibiotics and what the dosage would be? I am having trouble getting back into contact with the man I was speaking to at the squirrel refuge.
Any help or advice would be greatly appreciated.
