The moment your dog barks, a painless, harmless spray is released.
The spray makes a hissing sound and may be scented with citronella if
desired. Both the 'hiss' and the smell are disliked by most dogs.
The reservoir attached to the collar is refillable. The refills
can be purchased in 75ml or 150 ml sizes. In a few days, the dog
learns to keep quiet while wearing the collar and concentrate on more
normal activities. This Jetcare anti-bark collar is not suitable
for small dogs. It is also available in
mini size.
