Dr. Jay Bhattacharya, Director of the National Institutes of Health (NIH) under President Donald Trump, announced over the weekend that the agency has officially shut down its final beagle research facility, ending decades of controversial animal testing that had come under intense public scrutiny in recent years.
Speaking with Fox News host Rachel Campos-Duffy on Sunday, Bhattacharya said the agency is adopting new methods that are more relevant to human health, including the use of artificial intelligence and other emerging technologies to replace live animal experiments.
“It’s very easy, for instance, to cure Alzheimer’s in mice. But those things don’t translate to humans,” Bhattacharya said.
“So we put forward a policy to replace animals in research with technological advances, AI and other tools, that actually translate better to human health.”

When Bhattacharya confirmed that, “We got rid of all of the beagle experiments on NIH campus,” Campos-Duffy responded, “Amen.”
NIH later confirmed the development on social media, saying the agency is pursuing an “initiative to expand innovative, human-based science while reducing animal use in research, including getting rid of all the beagle experiments on the NIH campus.”
The decision comes after years of investigative work by medical watchdog group White Coat Waste, which uncovered disturbing details about experiments that resulted in the deaths of over 2,100 beagles in federally funded testing.

According to the organization, the experiments were conducted on-site at NIH facilities and included procedures where the dogs were intentionally infected with pneumonia-causing bacteria, subjected to septic shock, and killed after several days of suffering.
“The NIH pumps pneumonia-causing bacteria into beagles’ lungs, bleeds them out, and forces dogs into septic shock,” the watchdog group wrote in one report. “After four days of infection, NIH kills the beagles—and stuffs their bodies into a refrigerator.”
White Coat Waste Project Founder Anthony Bellotti issued a statement to the Daily Caller News Foundation in response to the announcement, saying:
“As the watchdog that first uncovered and battled Dr. Fauci’s beagle tests (the biggest animal testing scandal in history), we’re proud that White Coat Waste has closed the NIH’s last in-house beagle laboratory—and the U.S. government’s biggest dog lab. We applaud the President for cutting this wasteful NIH spending and will keep fighting until we defund all dog labs at home and abroad.”
The controversy over NIH’s animal testing gained national attention in 2021 after it was revealed that Dr. Anthony Fauci’s division at the agency had funded experiments at Kansas State University involving the injection of puppies with mutant bacteria, followed by exposure to ticks.
According to Breitbart News, the study resulted in the deaths of 28 beagle puppies annually, with total fatalities estimated between 126 and 138 dogs since the research began in 2007.
Another experiment exposed by White Coat Waste revealed that NIH had funded a project in Tunisia where beagles were drugged and had their heads locked in mesh cages filled with sand flies.
The insects were allowed to feed on the dogs while they were alive. In some instances, dogs were left alone in the desert in cages for multiple nights to attract infectious insects.
The Trump administration has taken steps beyond NIH to curtail government-sanctioned animal testing.

Both the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) have implemented new policies that reduce reliance on live animals in federal research.
The animal rights group PETA has acknowledged those changes, noting they could help “spare tens of thousands of animals each year.”
The closure of the NIH beagle lab marks a significant shift in the direction of federal research under the current administration. No comment has been made by Dr. Fauci or NIH officials associated with the past programs.
