the thing about this is that they stop digesting food, there metabolism shuts down completely. as do other normal bodily functions. I did take one of my frogs to the vet and the doc was for certain it was in fact red leg. that was the first sick frog i encountered, since I have had over 30 frogs die of this. Not one of them shed when the symptoms were present. Only 2 attempted to eat, those where the ones that lived longer then a few days in fact i had one live 9 months with this infection and it was the one i took to the vet and was diagnosed with chytrid. Yes he died in the end as did the rest of the wild caught American bullfrogs even though i did my best to keep them going the one who lived the longest was named hacksaw. hemorrhaging is what kills them. Bursting blood vessels, red spots, bruise type marks on them. Trust me on this you cant confuse reg leg with anything else. it is possible for them to shed no doubt. About 40 percent of carriers live with it. But to go as far as saying that the lack of shedding disproves they have red leg..... I think not.
