Bearded Dragons are generally hardy, but are still susceptible to various illnesses. Common ailments include parasitic diseases, calcium deficiency, respiratory diseases and stomach impactions. Insects, green foods and unclean conditions may cause parasites.

Signs of parasites include runny droppings and a bad odour. Respiratory problems can arise from too much or too little heat and are signified by mucus, raspy breathing with the mouth open and blocked nasal passages. However, these can be corrected by improving housing conditions and administering antibiotics.

Pregnant females may also suffer from egg binding, which can only be corrected by a vet.
