Nutrition Service

Welcome to the Nutrition Service at the UC Davis Veterinary Medical Teaching Hospital.

The service provides nutritional consultations for the following:

  • Pet owners who wish to consult a nutritionist
  • Other VMTH services to provide nutritional recommendations and feeding plans for their patients
  • Veterinarians outside of UC Davis

The clinical scope of the Nutrition Support Service includes:

  • Commercial diet recommendations
  • Critical care nutrition
  • Customized weight loss programs
  • Nutritional consultation for metabolic diseases
  • Evaluation and formulation of computer-generated, home-prepared therapeutic diets

About The Service

Clients within traveling distance to UC Davis can arrange a direct appointment with the Nutrition Service. Appointments are especially beneficial for patients in which traditional nutritional approaches have proven unsuccessful or for clients with a special interest in nutrition.

The service also conducts remote consultations through primary veterinarians. Veterinarians can contact the Nutrition Service by telephone, and many of our services are provided via telephone, email, videoconference, or fax.

Direct appointments
In order to strive for the most precise recommendations with positive outcomes, a minimal work-up of the patient’s health status must be performed prior to an appointment with the Nutrition Service. This generally includes a physical examination, complete blood count and biochemical panel including a T4, and may also include imaging, urinalysis, and biopsies depending upon the patient’s condition. Contact the service for more information.

Remote consultations
Unfortunately, unless a relationship has been established between the client and the Nutrition Service clinicians with a direct appointment, advice regarding disease management for specific pets cannot be provided directly to clients. Consults must be initiated by the primary care veterinarian who has the most current knowledge of the patient. A summarized medical history and detailed diet history, in addition to recent laboratory results are usually required prior to the initiation of a consultation. Client communication for such cases is handled by the primary care veterinarian.

Our Customized Approach
All cases undergo extensive medical record review, as well as evaluation of the dietary history including treats and supplements. The process can be quite involved, as strategies and products are evaluated for both safety and efficacy in light of clinical experience, as well as through research including scientific literature review. This preliminary assessment is followed by quantitative computer analysis of data. This process ensures the development of a comprehensive and truly customized nutritional management plan.

What is a Veterinary Nutritionist?
The American College of Veterinary Internal Medicine now includes Nutrition as its sixth specialty (until 2021, and since 1988, there was a separate American College of Veterinary Nutrition). The specialty comprises veterinarians who have undergone advanced clinical and research training in the field of nutrition. Many have a graduate degree in nutrition in addition to their veterinary medical degree. All have completed extensive residency training which involves intensive clinical, teaching, and research activities. Trainees are required to pass written examinations in order to obtain board certification. These specialists are uniquely trained in the nutritional management of both healthy animals and those with one or more diseases. Members of this specialty college add the suffix “Diplomate ACVIM (Nutrition)” and are Board Certified Veterinary Nutritionists®. The UC Davis School of Veterinary Medicine is fortunate to be supported by several boarded nutritionists and veterinarians training for the specialty. The large group of veterinarians enables the Nutrition Service to have unique programs such as a veterinary student rotation, an outside consulting service for practicing veterinarians worldwide, and an active receiving service for referred cases from general practitioners and specialists in other fields.
