HISTORIC: A Lab-Industry Veterinarian Convicted After PETA’s Envigo Investigation
Amid the rows of cages, as the barking swelled and the stench of waste hung thick in the air, cruelty was routine at Envigo’s Cumberland, Virginia, beagle facility. Without PETA’s undercover investigation, acts like the attending veterinarian’s botched attempt to euthanize a conscious dog as she bled from her legs, and her failure to stop a worker from killing a puppy with an excruciating injection into the heart, would have gone on in secret.

Now, Dr. Dawn Marie Gau, the former attending veterinarian, has been sentenced after pleading guilty to seven counts of cruelty to animals—crimes she committed against individuals who depended on her for care and protection.
Gau was sentenced to 12 months in jail—which was suspended—and put on supervised probation for seven years.
No penalty can undo the suffering inflicted on thousands of dogs or the enormity of the cruelty PETA exposed at Envigo’s beagle prison during Gau’s lucrative tenure there, but this sentencing marks a necessary step toward accountability in an industry that treats living beings as disposable tools.
PETA’s Investigation Exposed Widespread Suffering
When PETA’s undercover investigator first entered the massive breeding compound in Cumberland, Virginia, they found approximately 5,000 beagle dogs and puppies trapped in small, barren kennels and cages. Envigo workers didn’t provide the dogs with even the simplest comforts, such as walks, beds, or love. The sheds that housed them were so deafening that noise levels exceeded 117 decibels—louder than a rock concert—when hundreds of dogs barked at once.
During the investigation, PETA’s eyewitness found more than 350 dead puppies left inside cages with their mothers and siblings. The conditions were so cramped that some puppies were accidentally crushed by their mothers. Others fell through holes in the cages. Most of the puppies who fell into the drains died after being soaked with feces, bedding, and other waste.

How You Can Help Keep Animals Out of Laboratories
PETA’s findings at Envigo helped lead to the site’s closure, the first-ever federal convictions of an animal supplier for experimentation, more than $35 million in penalties, and the liberation of nearly 4,000 surviving dogs.
But thousands of other animals are still being bred to suffer in laboratories. You can help change this.
Please, urge your federal representatives to introduce legislation compelling the National Institutes of Health to implement PETA’s Research Modernization NOW, a workable roadmap to transition away from cruel and pointless experiments on beagles and other animals.
