What are the signs of dehydration in animals?

The signs of dehydration in animals include dry gums, sunken eyes, and lethargy, which provide clear indicators of fluid loss. Dry gums indicate a lack of moisture in the mouth, while sunken eyes suggest that the animal is not retaining adequate fluid. Lethargy demonstrates reduced energy levels, often a result of decreased hydration. Together, these symptoms are strong indicators that the body is not receiving enough fluids, which can lead to more severe health complications if not addressed.

Other choices, while they represent health issues, are not direct indicators of dehydration. Increased thirst and constant urination can occur in conditions like diabetes, but do not specifically indicate dehydration. Heavy breathing and rapid heart rate may suggest other respiratory or cardiovascular problems, rather than dehydration alone. A dull coat and excessive shedding can signal various health issues as well, including poor nutrition or skin conditions, but again, do not specifically point to dehydration. Overall, the correct choice highlights the most characteristic signs of dehydration that are readily observable in animals.
