Pettec Antibark Vibra Trainer Bedienungsanleitung Seite 23

Attaching the collar
The collar must be firmly attached so that the vibration feedback can
be applied effectively. You can test the correct attachment of the collar
by checking whether one or two fingers can still fit beneath the collar.
The prioritized position of the Antibark Vibra Trainer is right below the
snout of the dog.
Please take care that the collar is not too tight or the dog may ex-
perience difficulties breathing. Likewise, the collar should not slip,
otherwise the spray feedback may become ineffective.
