The death of a dog during a sales training demonstration for a medical device has caused an uproar among animal rights activists. PETA is calling for Micrus Endovascular Corp. (San Diego) to give "written assurance" that it will stop using animals for medical and sales training purposes after anÂ alleged unauthorized killingÂ of a dog at Cleveland Clinic in January. The United States Department of Agriculture is also looking into the matter. According to the Washington Post, the procedure, which induced a brain aneurysm on a dog to demonstrate a medical device that was supposed to help stop bleeding, wasn't authorized,Â and the hospital "bans such use of animals." A statement from PETA also noted that a high-tech silicone model could have been used instead of the dog.
