(JTA) — A week after a university commencement speaker was canceled because of a tweet claiming that Israel trains dogs to rape Palestinian prisoners, the allegation leapt into the pages of The New York Times.

The columnist Nicholas Kristof included the claim in a column alleging widespread sexual abuse against Palestinian prisoners in Israeli prisons.

Detailing the account of an unnamed Gaza journalist who says guards summoned a dog when he was imprisoned in 2024, Kristof writes, “He tried to dislodge the dog, he said, but it penetrated him.” Linking to a range of pro-Palestinian sources, he notes that other prisoners had recounted similar experiences elsewhere.

Israel has rejected all of the allegations in Kristof’s column, which has elicited condemnation from Jewish groups for what they say is a “a modern-day blood libel” even as some say they believe it is important to take seriously claims of abuse in Israeli prisons. The New York Times has stood behind the column and said Kristof’s column reflects rigorous reporting and standards.

Neither Israeli officials nor The New York Times have commented specifically on the dog-rape claim, and the newspaper and Kristof did not respond to the Jewish Telegraphic Agency’s requests for comment. But a canine training expert said the allegations seem implausible if not completely impossible.

James Crosby, a retired police lieutenant and canine aggression expert affiliated with Harvard University’s Canine Brain Project, told JTA that it was “highly unlikely that anybody is going to be able to train a dog to successfully commit a sexual assault.”

Crosby said dogs can be trained to carry out some behaviors that could be seen as sexual but he was much more skeptical of the central claim that Kristof described.

“You could train the physical behaviors of jumping up and moving the hips back and forth and so forth. That is not necessarily sexual behavior from a dog,” Crosby said. “The actual penetration and so forth, I think that would be a lot more problematic.”

Israeli human rights groups have separately alleged both sexual assault in security prisons and the use of dogs to intimidate and assault Palestinian prisoners.

Kristof is defending the claim that the two phenomena happen in tandem, tweeting on Tuesday, “To those who say that canine rape is impossible, despite the many Palestinians who have described it, I’d note that at least three different medical journal articles discuss rectal injuries in humans from anal penetration by dogs. Sigh.”

A handful of records in medical literature have concluded that injuries to humans came from being penetrated by a dog. A review of the cases included in PubMed, a medical research database, showed that most reflect instances where humans forced dogs to perform sexual acts on them, but one 2019 case report from Uruguay described injuries to a 6 year old girl that a physician attributed to the family’s pet.

Crosby said that he was unsure if it was biologically possible to train a dog to have an erection on command but stopped short of saying that training dogs to rape humans was “impossible.”

“I’m not saying it can’t happen because, I mean, I’m a retired police officer, and I’ve also been dealing with fatal dog attacks and dog stuff for a long time, and there are always people out there that are twisted enough to do what you don’t think they can,” Crosby said. “The depths of human stupidity and nastiness are just always unplumbable.”

Whatever the case, it’s clear that the dog-rape claim has escalated rapidly as a charge against Israel in recent months.

The accusation has circulated for nearly two years but became turbocharged only in the last month, according to Travis Hawley, a Jewish self-described “open source intelligence” analyst who works as a contractor for the U.S. Department of Homeland Security and is also affiliated with the Network Contagion Research Institute, a center affiliated with Rutgers University that produces research about how information spreads online. The institute referred him to JTA.

After seeing the discourse about Kristof’s column, Hawley decided to trace the claim’s path on social media. He shared his findings with JTA on Tuesday.

Hawley found that the claim made a brief splash on social media in 2024 before falling dormant until last month. The 2024 cycle stemmed from an interview with the director general of the Hamas-run Gaza Health Ministry posted by Al Jazeera’s Arabic-language X account in June, according to his research. The official said that Israelis “made these dogs carry out vile actions against these detainees.”

Al Jazeera’s post got relatively little traction on its own. But days later, the account “Suppressed News” shared it in English, increasing the spread and introducing the word “rape” into the online discourse.

The account TrackAIPAC, which opposes the Israel lobby’s influence on U.S. politics, shared that post, Hawley found, as did the journalist Ryan Grim, whose coverage often criticizes Israel, and Briahna Joy Gray, a former press secretary for Bernie Sanders’ 2020 presidential campaign who has frequently shared anti-Israel posts that have drawn allegations of antisemitism.

After the June 2024 cycle, the claim simmered online but was relatively inconspicuous compared to more prominent allegations against Israel, including that it was deliberately starving Palestinians in Gaza, a claim that Israel similarly rejected as a blood libel.

Then in March, Israeli authorities dropped charges against Israeli prison guards who had been accused of sexually assaulting prisoners at the Sde Teiman detention facility, in an incident caught on video that had shocked many Israelis, roiled the country’s security establishment and fueled allegations that Israel was seeking to cover up abuse.

Hawley found that Sde Teiman’s return to the news cycle provided “the contextual hook the dormant June 2024 dog-rape narrative needed to re-ignite.”

Weeks later, Euro-Med Human Rights Monitor, a Geneva-based NGO that Israel has accused of having affiliations with Hamas, issued a report promoting the allegation. The organization is frequently cited by critics of Israel, and some of its claims have overlapped with those of independent sources. But its reports have also argued that Israel exhumes Palestinians to steal their organs — a claim with no evidence that medical experts say is impossible.

Euro-Med’s founder and chairman, Ramy Abdu, had shared the dog rape allegation during the 2024 wave. Now his organization said it had interviewed former prisoners who had experienced the phenomenon themselves.

Just days later, the claim had its biggest moment online yet, when an Israeli living in the United States, a former UCLA researcher and prominent online anti-Israel influencer named Shaiel Ben-Ephraim posted that an Israeli source had confirmed the dog rape allegation to him. He did not name the source or offer any additional evidence.

Ben-Ephraim had long faced challenges to his credibility from pro-Israel voices, in part connected to his admitted record of misconduct. But Hawley said Ben-Ephraim’s post, which echoed comments the Israeli had made on a pro-Palestinian podcast days earlier, appeared pivotal to the claim’s ascendance. He said Ben-Ephraim had injected a crucial element to the claim structure: that Israelis, and not just Palestinians and their allies, believed the dog rape claim.

Before April, “it wasn’t some acceptable narrative. It was allegations and bots and stuff like that,” said Hawley, who emphasized that he could not say whether the allegation was true. “It took a couple viral moments in the last two months before you could call it, I guess, mainstream.”

Hawley’s findings lined up with those published independently last week by Eli Kowaz, an American-Israeli analyst who formerly worked at the Israel Policy Forum. Kowaz published an essay arguing that the dog rape allegation was not credible, several days before Kristof’s column.

“You can hold two things at once: that Israeli detention conditions have produced credible, documented abuse allegations warranting serious investigation — and that a viral claim about trained rape dogs, built on a collapsed case and an advocacy podcast, does not meet any serious evidentiary bar,” he wrote. “Choosing which claims to believe before examining them tells you what the ‘evidence’ was ever actually for.”

Days after Ben-Ephraim’s tweet, the dog-rape claim had such reach that Ramy Elghandour, a bio-tech entrepreneur who had been invited to give the commencement address at Rutgers University’s engineering school, included it in a tweet condemning Israel.

“They’ve committed genocide,” Elghandour wrote in the tweet, a response to a Democratic lawmaker’s vow not to allow additional military aid to Israel. “They’re running dungeons where they train dogs to sexually assault prisoners … Weapons embargo is the absolute minimum.”

His invitation to speak was rescinded, but the claim was still climbing. Days later, Kristof’s column was published, bringing the claim to a vast audience including many people who would not previously have been exposed to it but who may have followed Kristof’s award-winning, impactful career as a columnist reporting about the Darfur genocide, human trafficking and global poverty. As evidence, Kristof’s column cited the Euro-Med report and linked to Ben-Ephraim’s post.

The prominence of the platform surprised even Hawley, who routinely watches discourse cycles reach unexpected heights. “To go from very obvious anti-Israel-narrative people, and then to the New York Times directly, is like, OK, how do we make that big jump?” he asked.

To some critics of Kristof’s column, the answer is that a well oiled pro-Palestinian propaganda machine had worked exactly as intended.

“His attempt to slip a salacious ‘dog rape’ trope from reportedly Hamas-linked operatives into the paper under the guise of an opinion piece is a failure of basic gatekeeping,” tweeted Albert Aaron, a pro-Israel Jewish New Yorker who posted that he was canceling his subscription, in one representative social media comment.

“Kristof quotes people who celebrated October 7 and want Israel destroyed, and will lie to achieve that goal. We know how the lies in this story made their way into it, where they came from and what purpose they serve,” Haviv Rettig Gur, an Israeli commentator, said in a viral post in which he described feeling a sense of relief to encounter what he believed were obvious lies in Kristof’s column. One of them, he said: “Dogs did not rape anyone.”

Claims of dogs trained to rape have been attached in the past to some of history’s most vicious figures. The journalist Lawrence Wright wrote that Egypts used dogs to rape prisoners under the regime that fell during the Arab Spring in 2011.

Ingrid Olderock, a Chilean-born German, is known as “The Dog Lady” because of allegations that she trained German shepherds to rape female dissidents during the dictatorship of Augusto Pinochet in Chile.

And JTA reported in the 1980s about allegations that Klaus Barbie, the Nazi Gestapo leader known as the “Butcher of Lyon” for his brutality, had trained a dog to rape women.

Some who are inclined to believe the dog rape allegation about Israel say the stories about Barbie have difficult implications for those who reject the claim.

“Dogs were used to rape humans during the Holocaust. I did not expect Israeli propaganda to turn into literal Holocaust denial,” tweeted the progressive journalist Ziad Jilani in response to a Jewish physician who had written, “Dogs cannot anatomically rape humans. As a physician, I thought I would just point that out. Why are antisemites such idiots?”

The Pinochet example and others like it that allege canine rape of women is not relevant in the case of the prisoners Kristof spoke to, Rabbi Natan Slifkin argued in a Substack essay on Wednesday. Slifkin runs Israel’s Biblical Museum of Natural History, which reflects his passion for and expertise in zoology.

“Without getting into gruesome detail, suffice it to say that the stories were not comparable. There are physical differences between male and female humans, and physical and behavioral differences between male humans and male dogs, alongside other differences in circumstances and in the descriptions of what happened in each case,” Slifkin wrote.

Noting that allegations have also circulated that the Israeli military has trained sharks and eagles to surveil and attack Palestinians, he continued, “The general view of experts in canine behavior … is that dogs cannot be trained to rape men.”

While Crosby, the dog scientist, said he was familiar with accounts of law enforcement and military personnel using dogs to intimidate individuals, citing the illegal use of dogs at Abu Ghraib prison in Iraq, he said he had never encountered an example in his research of a dog raping a human being. If misconduct involving dogs is taking place in Israeli prisons, he said, he is skeptical of the specific claims of rape.

“I would be more focused on the idea that they’re doing it as a form of intimidation and harassment,” Crosby said, “rather than literally having the animals sexually abuse somebody.”
