Disorders of the temporomandibular joint (TMJ) have long been known as contributors to orofacial pain and dysfunction in a dog’s ability to maintain a good quality of life, including eating, drinking, vocalizing, and using their mouth for useful activities. Treatment of TMJ conditions—such as cancerous tumors, severe inflammatory diseases, and septic arthritis—have progressed significantly over the past decade with research and clinical breakthroughs by veterinarians dedicated to oral health.

Researchers at the UC Davis Weill School of Veterinary Medicine, led by Dr. Carrie Finno and graduate student Briana Brown, have reported the genetic cause of a fatal neurologic disease, equine juvenile spinocerebellar ataxia (EJSCA), in American Quarter Horse foals. A genetic test is available through the UC Davis Veterinary Genetics Laboratory (VGL).

A 2021 outbreak of leptospirosis that sickened more than 200 dogs in Los Angeles County reveals critical gaps in vaccination practices and raises broader concerns about the spread of the disease between animals and people, according to new research led by the University of California, Davis. 

The Center for Animal Locomotion and Innovation, or CALI, at the University of California, Davis, was flying high during its grand opening ceremony on Friday, May 8.  

A gate swings wide at the auction ring at the Yolo County Fairgrounds. A group of goats and sheep hesitate, then shuffle through. They move as a group; their bodies pressed against each other. Beneath it all is their ruminant instinct of wanting to return from where they came. Rancher Nathan Medlar, with NM Ranch in Auburn, has arranged these gates to accommodate that instinct.

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. 

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. 

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.

In February 2025, Nature Medicine published a startling report by a team of researchers at the University of New Mexico that estimated the human brain was 0.5% plastic by weight.

A major five-year study on California’s Central Coast led by the U.S. Food and Drug Administration and the Western Center for Food Safety at the University of California, Davis, is helping scientists better understand how harmful bacteria can move through the environment.
