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 you follow your veterinarian's feeding instructions carefully and feed only Prescription Diet y/d.
Ask your veterinarian for specific feeding instructions for your pet. 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.
For best results:
- Gradually transition to this new food for 7 days or more
- Exclusively feed the recommended Prescription Diet dry and wet foods
- Keep fresh water available at all times
- Have your veterinarian monitor your pet's condition
- To prevent suffocation, keep the packaging out of the reach of pets & children
