Hello Gaby. I am new to this forum or any forum for that matter. I am glad to see you have written only two weeks ago because it looks like no one has been on here since 2010. I am so sorry that your frog has the swollen lips. I am so sad and worried about my Pacific Tree Frog. He seems to be having the same problem with the swollen lips. I was wondering how your frog is doing now and if you went to the vet what did they do for you? Did the swelling ever go down? Did you ever figure out what the problem could be? I am not sure who sees frogs in my area but I need to find someone but for now I was hoping maybe you had any advice? I hope to hear from you soon.
