Climate change is likely to drive rodent-borne arenaviruses into parts of South America that have never faced these diseases, putting new communities of people at risk, finds a study from the University of California, Davis. 

Gathering fresh eggs laid by chickens in your backyard may sound idyllic, but keeping the birds healthy requires some special knowledge. Avian influenza, salmonella, predators, food safety, choosing the correct feed, what’s snake oil and what’s not, and how to pick the right breed for you are just some of the common chicken conundrums people want practical science-based information about.

Professor Pamela Lein co-authored two new research papers that help explain how biological systems respond to polychlorinated biphenyls (PCBs) exposure, including key differences between males and females.

An inherited form of blindness directly comparable to a common inherited optic nerve disease in humans has been discovered in rhesus macaques at the California National Primate Research Center at the University of California, Davis. The work, published April 15 in Proceedings of the National Academy of Sciences, could lead to a better understanding of autosomal dominant optic atrophy, or ADOA, and potentially to new treatments. 

As a world-class veterinary and research institution, UC Davis has many spaces that serve not only humans, but also horses and raptors and cats (oh my). Long before a beloved furry friend can get a state-of-the-art CT scan or a peregrine falcon can fly through an obstacle course to inform flight research, Design and Construction Management, or DCM, project managers work diligently and collaboratively to ensure each project is able to accommodate every creature that uses it. 

The California Wool Growers Association recently held its 106th Annual California Ram Sale in Tulare, and UC Davis livestock veterinarians and students were on hand to help facilitate the event. As they have done for more than 50 years, the school’s livestock team provided health checks on all 500 rams up for sale.

In 2016, then 4-year-old Mustang mare Magic was one of 279 wild horses rounded up by the Bureau of Land Management (BLM) following the massive Soda Fire in Idaho, which destroyed more than 279,000 acres of their critical habitat. To prevent their starvation, BLM rescued the wild horses. Between 2016 and 2019, many of the horses, including Magic, were adopted out, and others were returned to the wild when their grazing area grew back.

“He wasn’t doing normal dog stuff,” said Keri Sheldon about her experience in 2021 with Andy, her golden retriever/poodle mix puppy. “We noticed he was always guarded with other dogs and not playing normally. It gave us concern – he was not acting like a normal puppy.”

So, when he started whimpering after a mishap while playing, Sheldon and her partner Keith Fenech took the goldendoodle to their primary veterinarian.

“The vet took x-rays and diagnosed Andy with hip dysplasia,” Sheldon said. “I was quite upset to hear that.”

The UC Davis Weill School of Veterinary Medicine has received the second largest individual gift ever made to the school: $75 million from Bay Area residents Kathy Chiao and Kenneth Hao. 

Their gift will name the school’s new small animal hospital, which will provide cutting-edge veterinary care, accommodate more patients annually, and increase space for student and specialty training. Their gift will also fund scholarships, animal-human translational medicine, and programs for those unable to afford veterinary care.

Dr. Adriana Garzon, a third-year resident in the Livestock Herd Health and Reproduction Service, has been selected as the recipient of the 2026 American Association of Veterinary Clinicians (AAVC) Resident Award. The recognition is given annually to a resident in their final year of training who has achieved a high degree of excellence in their chosen specialty.

Among dog breeds, Nova Scotia Duck Tolling Retrievers (tollers) have an unusually high rate of Addison's disease, a condition in which the adrenal glands do not produce enough hormones, notably cortisol and aldosterone. In humans, Addison's disease is thought to occur when the body's immune system attacks the adrenal glands, making it a type of autoimmune disease.

Ty, a police K-9 seriously injured in the line of duty, is expected to make a full recovery thanks to rapid emergency response and advanced surgical care at the UC Davis Weill School of Veterinary Medicine.

Like many veterinarians, Dr. Waka Blair, DVM ’10, dreamed of working with animals as a child. She fondly recalls adopting abandoned kittens and telling her teacher she wanted to be a veterinarian. However, growing up in Osaka, Japan made that dream difficult to pursue and she realized early on that societal expectations wouldn’t allow it. Over time, her passion for animals faded–but a new love took its place: a fascination with America.
