My guinea pigs recently got off of Baytril for a URI, four days ago. Those four days ago, we got a recheck at the vet and they said everything sounded perfect. However, it's today that i still noticed some sneezing. I honestly can't tell if it's more than usual but I'm still worried that it could be back? Is this possible? The Baytril knocked the URI out fast, as i caught it early, but could it really be back already? I'm going on a trip tomorrow, leaving them at my grandma's house, where she won't be able to tell if they're ILL or not. Am i worrying too much, or should i be concerned? Please answer soon!
