Staywell Innotek Citronella Anti Bark Collar Kit

The barking control collar targets your dog's ultra-heightened senses
for immediate results.

Each time your dog barks, the microphone will detect the barking and
the barking control collar releases a harmless citronella spray.
 
The dog is instantly distracted by the sight, smell, sound, and
sensation of the gentle spray collar and stops barking.

Your dog becomes conditioned to expect the spray and will
instinctively refrain from excessive barking to avoid it.

Original spray device
