dory has her second RI in two months. Does anyone know of any preventative measures i can take to prevent them?
reptaid wont deal with the source of infection if your lizard does have a respiratory infection. Messing with remedies will only see the problem worsen.
If your animal does have a respiratory infection, its likely not another but the same issue which has not responded to baytril.
If this is the case I recommend another vet visit. Ask for a culture to be done to determin an appropriate drug to use.
