That is good news ! Need to follow-up with a fecal exam done by herp vet or lab. If food was not prolapse cause; then parasites are probably the culprit. Get fecals done on all frogs and medicate them as required. If no local vets; you can have the fecals done my mail and then contact Dr. Frye for meds (maybe he can do fecals too). Good luck !
