Frog|10 Common Diseases (cause → signs → examination → treatment direction → prevention)
Ten common diseases of the frog (White's tree frog/horned frog/clawed frog) gathered into one table: Red leg syndrome, Chytridiomycosis, Metabolic bone disease (MBD), Obesity and hepatic lipidosis, Chemical burn to the skin, Endoparasitism, Impaction, bacterial/fungal skin infection, Dehydration, and Trauma. Each row lists cause, signs, examination, treatment direction and prevention; the treatment column gives categories only, never doses. It suits checking against when something looks wrong and you need to narrow down the direction first, or when taking on a new animal.
This content is compiled from the disease table for the Frog (White's tree frog/horned frog/clawed frog) in the reptiles and amphibians chapter of the veterinary animal encyclopedia. The same sign calls for different handling in different species, and copying what is done for another species can be harmful — first confirm which animal you are dealing with.
| # | Disease (Chinese/English) | Cause | Signs | Examination | Treatment direction | Prevention |
|---|---|---|---|---|---|---|
| 1 | Red leg syndrome | Bacterial septicaemia caused by *Aeromonas* and similar organisms, triggered by environmental stress/poor water quality; a classic disease of amphibians | Reddening of the skin on the hind limbs and abdomen, lethargy | Visual examination, bacterial culture | Antibiotics require a prescription; this is an emergency | Maintaining water quality, avoiding stress, quarantining new animals |
| 2 | Chytridiomycosis | Fungal infection with *Batrachochytrium dendrobatidis*, a devastating disease for wild amphibian populations | Abnormal skin shedding, lethargy, abnormal posture | PCR testing of a skin swab | Antifungal medication requires a prescription | Quarantining new animals, avoiding mixing with wild-caught animals |
| 3 | Metabolic bone disease (MBD) | Calcium deficiency, lack of vitamin D3 (UVB requirements vary by species) | Softening of the bones, abnormal movement | Palpation, X-ray | Calcium supplementation assessed by a veterinarian | Balanced calcium and vitamin supplementation |
| 4 | Obesity and hepatic lipidosis | Common in horned frogs; prolonged overfeeding | Marked obesity, reduced activity | Blood biochemistry | Dietary adjustment plus medication, which requires a prescription | Controlling feeding frequency and portion size |
| 5 | Chemical burn to the skin | Chlorine or detergent residue in contact with the skin | Ulcerated skin, abnormal secretions | Visual examination | Emergency management by a veterinarian | Dechlorinating the tank, avoiding detergent residue |
| 6 | Endoparasitism | Poor environmental hygiene, wild-caught animals | Weight loss, reduced activity | Faecal microscopy | Anthelmintics require a prescription | Quarantine, regular faecal examination |
| 7 | Impaction | Ingestion of substrate (horned frogs are at high risk because they swallow prey whole) | Refusal to feed, abdominal distension | Palpation, imaging | Severe cases require surgery | Avoiding substrate that is easily swallowed |
| 8 | Bacterial/fungal skin infection | Poor water quality, a damp and unhygienic environment | Skin lesions, abnormal secretions | Visual examination, culture | Prescription medication from a veterinarian | Maintaining water quality and environmental hygiene |
| 9 | Dehydration | Insufficient humidity (tree frogs/horned frogs) or poor water quality (clawed frogs) | Dry skin, reduced activity | Visual examination | Fluid replacement assessed by a veterinarian | Maintaining suitable humidity/water quality |
| 10 | Trauma | Jumping into the glass of the tank | Trauma with bleeding | Visual examination | Management by a veterinarian | Protecting the tank environment, reducing startling stimuli |
The 10 rows above are copied cell for cell from the encyclopedia chapter, neither rewritten nor condensed; the treatment column gives categories only, never drug names or doses, and any medication must be prescribed by a veterinarian.

Limits of this content
This content comes from the reptiles and amphibians chapter of the veterinary encyclopedia (see the evidence chain for the original location and content hash). The sources at the end are the authoritative materials cited by that chapter; the correspondence is at chapter level, which does not mean every sentence is traced sentence by sentence back to a given source. This material is for education and cannot replace diagnosis and prescription by a practising veterinarian; in an emergency, seek veterinary care immediately. This text has not been clinically reviewed by a named veterinarian.
FAQ
- What is red leg syndrome, and what should make you call the vet at once?
- Bacterial septicaemia caused by *Aeromonas* and similar organisms, triggered by environmental stress or poor water quality; it is a classic disease of amphibians. You will see reddening of the skin on the hind limbs and abdomen, and lethargy. The direction of management is antibiotics, which require a prescription, and this is an emergency. This row belongs to the group in the source chapter that needs prompt attention; the actual judgement still rests with a veterinarian case by case, and this text gives no drug names or doses.
- What causes chytridiomycosis and what matters most in preventing it?
- Fungal infection with *Batrachochytrium dendrobatidis*, a devastating disease for wild amphibian populations. You will see abnormal skin shedding, lethargy and abnormal posture. Prevention rests on quarantining new animals and avoiding mixing them with wild-caught animals. The treatment direction must be assessed by a veterinarian case by case; this text gives no drug names or doses.
- What causes metabolic bone disease (MBD) and what matters most in preventing it?
- Calcium deficiency and lack of vitamin D3 (UVB requirements vary by species). You will see softening of the bones and abnormal movement. Prevention rests on balanced calcium and vitamin supplementation. The treatment direction must be assessed by a veterinarian case by case; this text gives no drug names or doses.
