Hey I just looked that stuff up, my only worry is if its prescribed by weight your dog would obviously weigh a lot more then frog so it could end up doing more bad then good. But if it isn't from what I have seen and read I would give it shot. And if your worried it could be to strong may be adding a 2-3 drops of distilled water to a drop of the medicine might lower the concentration abit. I'm not a vet so I don't really want to say yes but if it is ok I wouldnt want to say no, its totally up to you. Or you could wait till morning and just call a exotics vet explain your situation and ask them if your able to give it to him since you have it on hand. And if they don't want to answer there is a vet Named DR, Frye in the U.S that will sometimes give advice over email. I don't know the email of hand but you could send him an email with some pics and he would be able to tell you if your able to use that stuff.
