Hello DFM! After reading post and looking at pics, appears to me frog has a serious infection. My first recommendation is to take it to a Vet. If that option is not available to you; first thing to do is to become familiar with this article: Basic Frog First Aid. How long has frog shown these symptoms? Also, could you please provide answers to these questions: Trouble in Enclosure.

Can you get some: Baytril (Enrofloxacin) and plain pedialyte in the meantime? Others with more disease experience will chime in soon. Another option you have is to contact Dr Frye at (743)439-2273; he does consults and sells meds online. Hope that phone is right number because his website is currently down. Good luck !.
