The State Department's Office of Inspector General (OIG) found that more U.S. bomb-sniffing dogs than previously known had died overseas due to mistreatment.

The OIG in September published a report that found that at least 10 of the 100 explosive-detection dogs sent to Jordan between 2008 and 2016 died of "various medical problems," while others were living in "unhealthy conditions."

The report also recommended that the U.S. stop sending dogs to Jordan until a plan was put in place to ensure better treatment for them.

On Friday, the OIG released a follow-up report that stated that the department had "received notice of additional canine deaths that warrant immediate Department action," CNN reported.

Specifically, the report found that two canines died in Jordan between June and September of this year. One died from heat stroke, and the other died from insecticide poisoning.

Another dog mentioned in the report currently suffers from leishmaniasis, a treatable but potentially lethal disease that comes from insects such as mosquitoes, ticks and fleas, according to CNN.
