We’ll be with you every step of the way

A diagnosis of cancer in your pet can be overwhelming. Fortunately, as with human medicine, treatment options are available and our Oncology team is here to help you make the decisions that will provide the support and help to maximize the quality of your pet’s life. Each case of cancer is unique and we tailor each treatment plan to fit the individual needs of the patient and their family.

The Oncology team at Vista is here to provide cutting-edge diagnostics and treatments for any pet with cancer. This includes the ability to perform advanced diagnostic tests, including multiple modalities of tissue and bone marrow sampling, digital radiography, ultrasonography, and computed tomography. Our team works with board certified radiologists to provide the most comprehensive understanding of each pet’s cancer, so that the most appropriate treatments can be recommended. Our Surgery team is available to provide cutting-edge surgical procedures to help minimize complications associated with oncologic surgeries, and provide the best outcome for our patients.

At Vista, we recommend that you take an active role in your pet’s cancer diagnosis and treatment, and our Oncology team works to make ourselves as available as possible to provide excellent care for our patients and their families. We are also always available to discuss your pets’ oncology needs with your family veterinarian, prior to consultation with our Oncologists. We recommend that you give your pets once weekly “massages”, and always have any new lumps or bumps assessed by a veterinarian. Early detection of skin masses can be highly beneficial in the treatment of various types of skin cancer, so no mass should go unnoticed!

Kristen Couto, DVM, DACVIM (Oncology)

Dr. Kristen Couto had the dream of becoming a veterinarian for as long as she can remember, growing up in the household of a veterinary oncologist who mentored her through her years of vet school at The Ohio State University College of Veterinary Medicine.  Dr. Couto obtained her degree in veterinary medicine from Ohio State, graduating Summa Cum Laude in 2013 and went on to complete a small animal medical and surgical internship at North Carolina State University in 2014, which solidified her love for the “family business” of veterinary oncology.  She successfully completed a residency in medical oncology at the University of California, Davis and became board-certified in 2017.  Her research focused on canine lung tumors and a new form of gastrointestinal lymphoma that is becoming more recognized in dogs and she has a special interest in the human-animal bond and helping families through every aspect of a cancer diagnosis and treatment.

Outside of the hospital, Dr. Couto enjoys exploring the West Coast, hiking, trail running, and spending time in her new town of Winters, fixing up a 1920’s home.  In the past few years, she has been able to explore the Oregon Coast, see the Great American Solar Eclipse, hike Half-Dome in Yosemite, and camp throughout Nevada and Utah on her most recent road-trip, her final destination being the beautiful canyons of Zion National Park.  She shares her home with two dogs, a Puggle/Pit-bull mix named Gob and a Black Lab mix named Sophia, and one cat named Oink, who have been troopers during  her multiple cross-country moves!

Dr. Couto is available for consultations on Monday through Thursday.
