Hello everyone! I've been using the doxy/baytril combo to treat my rat for URI and now she's approximately 2 years old and the combo has stopped working. I'm planning to move on to baytril/zithromax combo after consulting my vet. Can anyone answer me these 2 questions: 1. for baytril 0.5 % she'll need 0.66 mL twice a day, is that correct? 2. for zithromax 200mg/5ml the dosage is 0.17 ml twice a day? I want to make sure those are the correct dosages because in the past my vet has given my ratties too low dosages for a few days... Thank you everyone in advance!!
