How can I tell if my tortoise is dehydrated?

Dehydration in tortoises can appear as sunken eyes, thick saliva, dry skin, or reduced activity. A dehydrated tortoise may also pass very firm or minimal waste. Regular soaking for appropriate species and access to fresh water helps maintain hydration. Environmental humidity also plays an important role. If signs persist despite proper care, veterinary evaluation is recommended. Early detection prevents more serious complications.
