Morning! I have a porcelain that has been sneezing for a good month now. He has only a little bit of a wet nose. He is eating and drinking and going out just fine. Just sneezing quite a lot. I have a few others that do it but not nearly as much as him. I changed their bedding from straw to pine shavings, but he was sneezing before I did that. Do I need to put antibiotic in their water? I put some of the tetracycline in for about a week but no change. Any help would be great!
