Hi all. One of my guinea pigs was recently diagnosed as having a chest infection and the vet gave me baytril, 0.4ml twice a day. He really perked up and went from eating very little to having his appetite back. He now seems fine in himself but I'm just not convinced hes fully over it. He still sounds slightly raspy. Ive been searching the forum and have seen Zithromax mentioned and just wanted a bit of advice really. I will be going back to the vet to check everything okay so should I mention Zithromax? Also if you all think this is a drug worth trying but the vet disagrees is there anywhere online I could purchase it? Thank you in advance for your help.
