What are the signs of dehydration in animals?

Dehydration in animals is assessed through several clinical signs that indicate insufficient fluid levels in the body. The correct choice highlights key indicators: dry gums, lethargy, and decreased skin elasticity.

Dry gums are a critical sign because they indicate that the mucous membranes are not receiving adequate moisture, a common consequence of dehydration. Lethargy, or a noticeable lack of energy and alertness, often accompanies dehydration since the body lacks sufficient fluids to maintain normal metabolic processes and physical activity. Decreased skin elasticity is another significant sign; when an animal is dehydrated, the skin loses its ability to return quickly to its normal position after being pinched. This is often assessed by pulling up a fold of skin—when hydrated, the skin retracts promptly, while dehydration can lead to a slower response.

In contrast, the other choices involve signs that do not align with dehydration. Increased activity and bright eyes can indicate good health or increased energy levels, rather than a deficiency in hydration. Excessive drinking and frequent urination are typically signs of conditions such as diabetes or other metabolic disorders, rather than dehydration itself. Additionally, a shiny coat and vibrant energy suggest that an animal is well-hydrated and healthy, which is clearly opposite the state of dehydration
