I took my male, around 3 month old, guinea pig to the vet about three weeks ago because he was sneezing so much and exotic vet prescribed him bactrim twice a day for ten days. After four days of being on it, he seemed to be getting worse so I took him back in the checked his lungs and everything seemed to be fine. December 26th was the last day he got his antibiotics and it's been around a week now and he is still has wet sneezes (by that I mean when he sneezes liquid sprays a little bit). He is still eating and has an impeccable appetite, drinks normally, and is a HIGHLY energetic guinea pig. He constantly popcorns and runs all about. When I went to see the vet the second time he said he didn't want to give him baytril because he was worried about his bones and he told me that it could just be a virus and there is nothing they could do about that and if it was it would have to just run its course, like a common cold.
Should I still be worried ?
