The standard dose for boids is 2.5 mg per pound body weight. However, this should be determined and prescribed by a reptile qualified vet. Also of importance, the entire "curtus" group (brongersmai, breitensteini, and curtus) all show a higher than normal sensitivity to many antibiotics and when using Baytril, they should never be dosed more frequently than once every 48 hours, and with some other antibiotics, once every 72 hours. Additionally, Rich is quite correct in that the actual amount in cc's to be injected can be different with the exact same antibiotic depending on the actual concentration in mg per cc in the original stock solution supplied. Unless you are experienced in making drug dosage calculations in metric units and weights, get the assistance of a vet. As Rich said, mistakes can lead to serious consequences. This can be true for under dosing as well as overdosing. Good luck.
