Trusted by veterinarians.
GUIDED by independent experts.

Rayne diets are formulated through the collaboration of some of the top experts in animal health and nutrition. The professionals in this Clinical Advisory Team (CAT) — composed of independent experts across a wide range of veterinary specialties like nutrition, oncology, and cardiology — formulate our diets based on peer-reviewed science to have multiple indications.

Outside of a few restricted formulas intended for short-term feeding for diagnostic purposes, we formulate our diets to meet—and often exceed— AAFCO nutritional profiles. CAT’s expertise helps hold us to what we believe is a higher standard than either the AAFCO feeding trials or the AAFCO nutritional profiles. We confirm every diet that does meet the AAFCO Nutritional Guidelines via independent third-party testing and analysis.

Our goal with our formulas is to nourish healthy pets as well as aid the most sensitive patients and complex cases.


how our diets are formulated:

 

1

A veterinary internal medicine specialist designs the goal "key parameters" for a diet - this is the ideal range of amount of protein, fat, phosphorus, etc. As board certified specialists, the internists working with Rayne are familiar with caring for the most complex and challenging cases. They are keenly aware of the role in the medical management of patients, and in keeping healthy pets happy and healthy.

 

A PhD nutritionist reviews the goal formulation and begins to select which ingredients will provide the end nutrients the internist wants.

3

Other experts will be brought into the formulation to help make decisions on which ingredients to use. For example, when developing a novel protein diet, a dermatologist will be consulted to guide protein and carbohydrate choices.

 

4

A board-certified veterinary nutritionist reviews the nearly final formula to give her advice, suggestions, and comments.

 

5

The formula is complete and ready for test runs! This is a long process with a lot of back and forth, but the end result is a diet that the entire team is very excited to bring to the market.


Some pet food companies keep veterinary nutritionists on staff. We believe this leads to bias, as someone beholden to their employer is less likely to risk disrupting the status quo. Our consultants aren’t dependent on Rayne for a paycheck, and thus can hold us to the highest standards in doing what’s right for pets.
