Companion Animal Diet Consultation
Many of the dietary needs of your companion can be obtained by feeding a general over-the-counter or therapeutic commercial diet. However, in many cases, supplementation or increasing specific components in the diet are beneficial to maintaining or optimizing health. We are available to discuss your pet’s nutrition and how it affects the health and longevity of his/her life.

  • Obesity Consultation
    Obesity prevention can help eradicate many medical and surgical problems that we see every day and also improve and extend your pet’s quality of life. Obesity management is achieved through strategies to achieve satiety, attention to calorie intake, and knowing the weekly percentage of weight loss. We provide a detailed weight loss program for your pet, which includes recommendations for therapeutic or over-the-counter calorie restricted diets and the proper feeding guidelines. Our assistance can help your pet lose weight safely and effectively.
  • Homemade Diet Formulation
    Many clients are interested in cooking for their companions. We often recommend feeding commercial products, however there are various disease entities and client concerns that warrant homemade formulations. We can provide recipes that are grain-free, gluten-free, or vegetarian for interested clients. Every pet’s nutritional needs differ, so we are happy to design a detailed and well-balanced diet specifically for your loved one.
  • Parenteral Nutrition Consultation
    In critical illness or situations in which your companion is not meeting the caloric requirements, intravenous nutrition may be required. Adequate and proper nutrition is very important for pets that are hospitalized and has a great impact on a pet’s attitude and the healing process. If you feel that your pet is in need of this service, please ask your primary clinician for a referral to our service.

The Medical Oncology Service at Cornell first saw clinical patients in July of 2000. The Oncology Service sees approximately 1,000 cancer patients a year. A state of the art linear accelerator with a multileaf collimator became operational in October of 2002 and we currently irradiate approximately 100 patients a year. The radiation facility includes a CT-based 3D radiation treatment planning system that allows us to optimize the radiation treatment plan for individual patients. Dogs and cats with cancer are evaluated through the oncology service which may include but is not limited to blood work, radiographs, tumor biopsy and staging, CT scan or MRI. Chemotherapy and radiation therapy are provided through the oncology service. Surgical procedures other than biopsies are done through the Surgery Service although the Surgery Service is consulted as necessary at the time of the Oncology appointment.

Oncology is a requirement for all veterinary students at Cornell University College of Veterinary Medicine. A didactic lecture course is provided for the third year veterinary students, and the fourth year veterinary students rotate through the clinical service in 2 week blocks. Radiation oncology and medical oncology residency training programs are available at Cornell University. A number of funded or partially funded clinical trials are ongoing through the Clinical Oncology Service.

Sports Medicine and Rehabilitation

Frye, Christopher W.
Miller, Allison
Wakshlag, Joseph J.

The Sports Medicine and Rehabilitation Service treat canine athletes, as well as other companion animals including cats, to recover from injuries or surgeries where rehabilitation is indicated to improve function and recovery.  The service works heavily with orthopedics and neurology services in the hospital to expand upon current treatment options depending on the ailment of your pet.  Whether serving athletes or everyday companions, the service focuses on helping animals recover performance abilities and stay active at any age.
Sports medicine for animals is an interdisciplinary field that integrates several modalities to help patients in ways one specific service may be limited. Sports medicine also offers an extra level of expertise and some procedures that typically can’t be found in most general veterinary practitioners’ offices.  The program offers several treatment modalities, including extracorporeal shockwave therapy for certain orthopedic conditions, platelet rich plasma therapy for osteoarthritis and tendon ailments, therapeutic ultrasound for deep tissue heating, transcutaneous electrical nerve stimulation (TENS), acupuncture and electro-acupuncture for pain relief, underwater treadmill for strengthening and muscle memory, and class IV laser therapy for wound healing and certain osteoarthritis conditions.
