Why does a bearded dragon's foot sweel up?

A bearded dragon's foot may swell due to various reasons, including injury, infection, or an underlying health issue such as metabolic bone disease. Injuries like fractures or abrasions can cause localized swelling as the body responds to trauma. Additionally, bacterial or fungal infections can lead to inflammation and swelling. If swelling occurs, it's essential to consult a veterinarian for accurate diagnosis and treatment.
