Nutritional Assessment
Nutritional Assessment Is an Iterative Process: Screening Evaluation
Each dog and cat can benefit from a nutritional recommendation ꟷ a recommendation that clients say they want, including for their healthy pets. To make an appropriate recommendation, however, it is necessary to perform a nutritional assessment. Steps in performing a nutritional assessment include evaluating the patient, the diet, feeding management and environmental factors; making a specific nutritional recommendation; and reassessing the patient and recommendation as needed.
Key Messages
- A screening nutritional assessment can be easily integrated into existing clinic protocols for patient consultations or appointments. A good physical examination already includes many components of a screening evaluation.
- A screening nutritional assessment includes:
- Body weight
- Body condition score
- Muscle condition score
- Complete diet history
- Abnormalities identified during physical examination
- A healthy pet without nutritional risk factors needs no further nutritional assessment, just a nutritional recommendation. However, an extended nutritional assessment is necessary if a patient has one or more nutritional risk factors, such as a medical condition, an abnormal body condition or muscle condition score, or is consuming an unconventional diet (e.g., home-cooked or raw diet).
- Before making a nutritional recommendation, evaluate the existing diet, feeding methods and environment to determine appropriateness for the pet. Consider the answers to these and other questions:
- Is the diet nutritionally complete and balanced?
- Given the pet’s estimated maintenance energy requirement, is the current amount of food and treats provided appropriate?
- Do calories from treats, human foods or supplements represent more than 10% of the total daily calories?
- Is food provided in measured amounts, regardless of whether the pet is fed free choice or meals?
- Does the pet have to compete for food within a multi-pet home?
- The nutritional or dietary evaluation and recommendation should include the pet’s main food, treats, table food, feeding method, frequency and location. If no changes are needed, let the owner know, as this provides positive reinforcement of what the owner is doing. Whether or not changes are needed, be sure to document the specific recommendation in the pet’s medical record.
