Which instruction governs the food, weight, and stool charts for Military Working Dogs (MWDs)?

The correct choice is OPNAV 5585/8, which specifically governs the food, weight, and stool charts for Military Working Dogs (MWDs). These charts are crucial for monitoring the health and nutritional needs of MWDs, as proper diet and weight management are essential for their performance and overall well-being. This instruction outlines the necessary protocols to effectively track these variables, ensuring that handlers have a clear record to refer to regarding the dietary and health status of the dogs under their care.

In contrast, the other options pertain to different aspects of MWD management or documentation but do not focus specifically on the food, weight, and stool charts. Each OPNAV instruction serves a distinct purpose, making it vital for handlers and command staff to reference the correct instruction to maintain the operational readiness and health standards of Military Working Dogs.
