Why did my bearded dragon die – 40 Common Causes of Death in Bearded Dragons

Why did my bearded dragon die

Losing a pet can be very tough. Here are some common causes of death in bearded dragons along with ways to prevent them:

  1. Impaction: This occurs when a bearded dragon ingests substrate or foreign objects. To prevent it, use non-particulate substrate like reptile carpet or tile.
  2. Metabolic Bone Disease (MBD): A deficiency in calcium and/or Vitamin D3. Ensure proper UVB lighting and provide a calcium supplement.
  3. Respiratory Infections: Usually caused by improper temperatures or humidity. Keep the enclosure clean and maintain proper temperature and humidity levels.
  4. Parasites: Internal parasites like pinworms or coccidia can be deadly if left untreated. Regular fecal exams by a reptile vet and proper hygiene can prevent this.
  5. Dehydration: Inadequate access to water or dry environments. Provide a shallow dish of fresh water and ensure proper humidity levels.
  6. Overheating: Excessive heat can lead to heat stroke or organ failure. Use a thermostat to regulate temperatures and provide a temperature gradient in the enclosure.
  7. Underfeeding/ Malnutrition: Poor diet or insufficient feeding. Offer a varied diet of insects, leafy greens, and occasional fruits.
  8. Burns: Incorrect placement of heat sources or hot surfaces. Use proper heating elements and monitor temperatures closely.
  9. Egg Binding: Females can become egg-bound if they are unable to lay eggs properly. Provide a suitable nesting area and consult a vet if your female shows signs of distress.
  10. Toxicity: Ingestion of toxic plants or substances. Research safe plants and avoid using pesticides around your dragon’s enclosure.
  11. Stress: Environmental changes, handling, or bullying from tank mates can cause stress. Provide hiding spots and minimize handling during stressful times.
  12. Fatty Liver Disease: Caused by a diet high in fats and low in nutrients. Feed a balanced diet and avoid excessive fatty treats.
  13. Trauma: Accidents or injuries from falls or improper handling. Handle with care and provide a safe enclosure with smooth surfaces.
  14. Reproductive Issues: Egg-laying complications or reproductive organ diseases. Avoid over-breeding and ensure proper husbandry for breeding females.
  15. Kidney Failure: Can result from dehydration, poor diet, or genetics. Maintain proper hydration and offer a balanced diet.
  16. Septicemia: Bacterial infections that enter the bloodstream. Keep the enclosure clean and provide proper hygiene for your dragon.
  17. Neoplasia: Tumors or cancers. Regular vet check-ups can help detect early signs of illness.

  32. Gastrointestinal Blockage: Ingestion of large or indigestible objects. Offer appropriately sized prey and monitor feeding closely.
  33. Dystocia: Difficulty laying eggs. Provide a proper nesting area and seek veterinary assistance if your female exhibits signs of distress.
  34. Fungal Infections: Often caused by improper humidity levels or poor hygiene. Maintain proper humidity and cleanliness in the enclosure.
  35. Insecticide/ Pesticide Exposure: Contamination of food or environment with toxic substances. Use organic or pesticide-free food sources.
  36. Over-supplementation: Excessive use of vitamin or mineral supplements. Follow recommended dosages and consult a vet if unsure.
