Feeding Guide

How to adjust feeding amounts to maintain optimal weight.

IMPORTANT: Because iodine intake from other food sources -- treats, another pets food, flavored medicines, etc. -- can compromise the effectiveness of low-iodine nutrition, it is critical that your client exclusively feed Prescription Diet y/d.

Provide specific feeding instructions for your patient.

Daily Feeding Recommendations are only a guide and a place to start.

Grams are the most accurate form of measurement; cups are estimated from grams.

Monitoring your patient's condition will assure the nutritional recommendation provides the best results.

Gradually transition to this new food for 7 days or more.

Reinforce with clients to feed Prescription Diet dry food, canned food, & treats exclusively.
