IMPORTANT: Because iodine intake from other food sources – treats, another pets food, flavoured 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.
