What is a Veterinary Nutritionist?

A Board-Certified Veterinary Nutritionist is a licensed veterinarian who has also undergone additional training in the nutritional management of both health and disease in animals. A Veterinary Nutritionist can help owners understand the fundamental causes and associations of specific dietary needs that can be used to help manage and, in some cases, prevent specific diseases that occur in dogs and cats. A Veterinary Nutritionist can also identify the optimal diet and supplement combination for an individual animal and when needed can formulate a home-prepared diet to meet that individual's dietary needs. A Veterinary Nutritionist works closely with your family veterinarian and/or other specialists to provide your pet with the best care possible.

Why and When Do You Need a Veterinary Nutritionist?

Your family veterinarian can give excellent advice about the best foods to feed your pet for general wellness as well as to help manage certain uncomplicated medical conditions, but a Veterinary Nutritionist will have a deeper knowledge of how medical conditions can affect nutrient requirements and how to balance the nutritional needs for animals with multiple medical needs. A Veterinary Nutritionist can help formulate or find diets that will aid in combating certain diseases and help promote general wellness. A Veterinary Nutritionist will choose a diet that takes into account the unique nutritional needs of your pet considering their age, breed, health history, and overall activity level. Your family veterinarian or other specialists may refer you to a Veterinary Nutritionist, but a referral is not required to make an appointment with MASH Nutrition.
