Border collies are highly trainable, greyhounds love to chase, and German shepherds make good guard dogs. While the environment plays a role, traits like these are highly heritable. A new study identifies 131 genetic variants associated with breed differences in behavior.
Identifying a gene for canine night blindness
An international team of researchers led by the School of Veterinary Medicine’s Keiko Miyadera has identified the gene mutation responsible for a form of night blindness in dogs. Strategies to treat this condition could also inform treatment of other diseases that rely on targeting this cell type.
Is treatment forever? Success of gene therapy for inherited blindness depends on timing
An FDA-approved gene therapy for Leber congenital amaurosis, an inherited vision disorder with a childhood onset and progressive nature, has improved patients’ sight. But new research underscores the importance of further investigation to halt the progression of the disorder.

Lung cell transplant boosts healing after the flu
A serious case of the flu can cause lasting damage to the lungs. In a study in mice, researchers found that transplanting cells from the lungs of healthy animals enhanced healing in others that had had a severe respiratory infection.
100th puppy
An 8-week-old black Labrador retriever is the 100th puppy to enter the Penn Vet Working Dog Center research-based training program.
Keeping parasites from sticking to mosquito guts could block disease transmission
Researchers at the School of Veterinary Medicine show how a new model for studying the way parasites known as kinetoplastids adhere to mosquitoes’ insides could illuminate strategies for curbing diseases.
