The FDA recommends against using the human version of the Loop over tissue known to contain implanted electrical leads, such as pacemakers. As such, we recommend against applying the Loop to animals who have pacemakers. If you are a pet owner with a pacemaker or other implanted medical device, when holding and treating your animal with the Loop, you should position the Loop BELOW YOUR WAIST (if you have a pacemaker), or at least six inches away from the implanted device.
