Sniffer Panels
Sniffer panels help to keep neighboring horses at peace. They essentially
separate the horse's heads.
Sniffer panels are inserted from the front, and easily clip on to the
partition between stalls. The panels can be snapped on during flight if problems
become apparent.
While not necessary for all horses, it's typically wise to keep a few on
hand, particularly when shipping many horses on longer flights, in case
separation becomes necessary.
