Warning Dr Frye

[Lija]

I am not getting why are you so upset. You didn't want to go to local vets if I remember correctly. Different countries, different states, different provinces, different laws. Here in Canada none of the vets would consult over the emails, drugs that are over the counter in US are by prescription only here, that applicable not only to veterinary medicine, but for human medicine too. People who suggested you to contact Dr. Frey were probably not aware you live in different country or just didn't realize the border restrictions.
I don't know your current situation, but in both Edmonton and Calgary there are vets who work with amphibians and know what they're doing. If your frogs are sick you should seek in person consultation and treatment.
