How can you assess the hydration level of a dog?

Assessing the hydration level of a dog is best accomplished by evaluating skin elasticity and the moisture of the mucous membranes. When a dog is properly hydrated, the skin will return quickly to its original position when gently pinched, indicating good skin turgor. Additionally, moist mucous membranes, such as those found in the mouth, are an indicator of adequate hydration.

In contrast, the other methods listed are not reliable indicators of hydration status. For instance, measuring the weight of the dog before and after an exam can provide some information, but it does not directly assess hydration levels and may be affected by various factors unrelated to fluid balance. Checking the dog’s reaction to commands provides insight into its training responsiveness and cognitive state, not its hydration status. Observing a dog’s appetite can reflect its general health or wellbeing but does not give specific information about hydration levels as a dog may be hungry yet still dehydrated. Therefore, assessing skin elasticity and mucous membrane moisture is the most direct and effective method for determining a dog’s hydration level.
