What is a primary indicator of an animal's overall health during a physical examination?

Coat condition and hydration status are key indicators of an animal's overall health during a physical exam. A healthy coat can reflect nutrition, grooming, and general well-being, while issues such as matting, excessive shedding, or changes in color can signal underlying health problems. Hydration status is crucial as well; signs of dehydration, such as dry mucous membranes, skin elasticity, and reduced urination, can indicate serious health issues that need immediate attention. Therefore, assessing both coat condition and hydration provides valuable insights into the animal's health status, allowing for appropriate interventions if needed.

Other indicators like weight, behavior, or activity level can be informative but do not offer the same immediate and clear assessment of health as coat condition and hydration status.
