This information being reported by NEWSWEEK after John Greenewald of the BLACK VAULT got secret documents after a FOIA request was answered..
From the article:
Newly released files from “behavior modification,” or mind control, projects conducted as part of the infamous Project MKUltra reveal the CIA experimented in more than controlling humans with psychotropic drugs, electrical shocks and radio waves—they also created field operational, remote-controlled dogs.
The documents were provided under the Freedom of Information Act (FOIA) by John Greenewald, founder of The Black Vault, a site specializing in declassified government records. In one declassified letter (released as file C00021825) a redacted individual writes to a doctor (whose name has also been redacted) with advice about launching a laboratory for experiments in animal mind control. The writer of the letter is already an expert in the field, whose earlier work had culminated with the creation of six remote control dogs, which could be made to run, turn and stop.
