An extended nutritional assessment is an opportunity to gather a more comprehensive nutritional history and pursue clinical diagnostics (Table 5). The specifics of an extended assessment will depend on abnormal physical exam findings, the information obtained through the screening nutritional history, and identification of specific nutritional risk factors. The development of nutritional recommendations provides an opportunity for the skills of the entire veterinary team to be utilized.
