What are the signs of dehydration in wildlife?

The signs of dehydration in wildlife are critical to identify for their health and recovery. Sunken eyes, dry mucous membranes, and decreased skin elasticity are specific indicators that reveal a lack of sufficient hydration in an animal.

Sunken eyes occur because as fluid levels in the body drop, the tissues around the eyes may lose support, causing them to appear retracted. Dry mucous membranes can be observed in areas such as the mouth, which normally should be moist; when dehydrated, these membranes become dry and can indicate serious health issues. Decreased skin elasticity is assessed by pinching the skin; if it does not return to its normal position quickly, this suggests dehydration, as hydrated skin should bounce back promptly.

The other options don’t accurately reflect signs of dehydration. Rapid breathing can be related to various other health issues, increased appetite does not correlate with dehydration (in fact, animals may eat less when dehydrated), and active behavior is usually indicative of a well-hydrated and healthy animal. Thus, recognizing the correct signs of dehydration is essential for effective wildlife rehabilitation.
