Lentek Bark Free Original uses corrective ultrasonic tones heard only by the offending pooch to help control dog barking both inside a home and outside, depending upon placement of the bark stopping unit. If it's your next door neighbor's dog that is causing you to lose sleep mount this Lentek Bark Free Original nearby to control dogs' nuisance barking day or night. Does no harm to the pet, unlike a shock collar, which could be dangerous for an old dog.

Bark Free sits on a counter or mounts outdoors. Activation is automatic. Barkfree's microphone picks up a dog's bark and generates a corrective tone dogs dislike.

Persistent barking and bad behavior in dogs is difficult to stop. Bark Free, developed by USA veterinary technicians, is a humane and effective in helping cure dog behavioral problems.

When placed near a neighbor's or your dog, Bark Free turns on automatically when barking occurs. Bark Free uses a unique "Bark Pickup Sensitivity Adjustment Selector" that the user sets to activate to the dog's bark. The selector rejects false sound readings and turns off automatically when barking stops.

Bark Free added a specially designed "Audible Sound Selector." You choose either an ultrasonic frequency heard only by dogs or lower sound tones audible to human ears. Both sounds proved effective with barking dogs.

Expected Results:
No method stops barking 100%. This includes the BarkFree. The overall amount of barking, especially night barking, should be significantly decreased within a few days after using the Barkfree. If you have not noticed this, your dog problem may be more serious than unnecessary nuisance or boredom barking. Many dogs do require a 4 to 6 week training period with Barkfree. One customer noted her very large, very smart purebred dogs barked louder and longer for two weeks before responding to the Bark-Free.

NOTE: Bark-Free devices seem less effective with Schnauzers and Yorkies. (Per our customers' experience.) Also use Bark-Free as reinforcement after using other nuisance barking reduction options such as intensive repetitive training by owner with or without Dog Dazer or Pet Agree (manually activated ultrasonic trainer); shock collars; and/or surgery to clip vocal cords.
