Hmmm, that's too bad because chronic prolapse is really a serious health problem. The vet says there's nothing they can do ? Can you find a more experienced vet ? If you Google LafeberVet.com prolapse in reptiles there's a lot of info as to the causes and types of prolapses as well as treatments. Extra
hydration is always good, so definitely give baths. Always make sure the tissue is clean before you push it back, and be sure that her food items are smaller than usual. The dragon really needs an expert vet, in the mean time extra
hydration may help just by making it easier to expel her wastes. But check the site that I mentioned and have your vet look at it as well. Best wishes for a good outcome !
