my god, that is bad, really bad ((((((((( on top of what was said the frog seems to be very small for 8month old, but there's nothing really to compare, i might be wrong. although with MBD that bad it would explain the size.....

please do what you were advised, but you need to take a frog to a vet asap, you won't be able to deal with that on your own, that is very bad case to deal with even for experienced keeper.
