Hi! My guinea pig Fred was sneezing more than normal, and rubbing at his nose like it was itchy, so I brought him to the vet who diagnosed him with an upper respiratory infection. He was on orbifloxacin (I’m in the United States so antibiotics may have different names than in the UK) once a day for two weeks but it didn’t seem to make a difference. He was no worse, but still very sneezy. So now we’re on day three of sulfamethoxazole twice a day and he’s supposed to be on it for 7 days, though I’m not sure I notice any difference yet. I’m just wondering if it’s possible for a guinea pig to have allergies? Or is it really this hard to get rid of a URI in a piggie? And if so does anyone have any tips on how to clear it up? I feel badly pumping him full of antibiotics like this, and I did just order him a probiotic that should be here tomorrow. Any advice is much appreciated- thank you!
