This ailment requires a visit to the vet, or at least a fresh stool sample being taken to the vet. The vet will determine what kind of parasites the animal might have and prescribe the proper medications to eradicate them. The true name of this disorder is Nutritional Secondary Hyperparathyroidism. Symptoms of metabolic bone disease include muscle tremors, spontaneous bone fractures, skeletal deformities, and inadequately calcified eggs. Snout damage and banging can lead to infection, mouthrot and major tissue damage.
Severe injury can result in tissue being rubbed off, and even bone infection and bone death.
The tissue and bone will not grow back if it is damaged. Preventing snout rubbing behaviour is the key to preventing such damage. I have also created a page dedicated to recognizing snout damage and resolving the problems that cause it, please visit the Snout Rubbing- Effects of, and Prevention page for more information. Most often seen in water dragons with snout damage, or systemic infections due to improper environment or stress. If this ailment is not taken care of properly at home or by a vet using prescribed medications it can lead to systemic infection and death.
