Review on DogRook Humane Anti Barking Training Collar - Vibration No Shock Dog Collar - Stop Barking Collar for Small Medium Large Dogs - Best No Barking Control Dog Collar by Renae Lockwood

IT WORKS! If you follow the instructions up to the "T" and make sure the fit is correct (not too loose - only 1 finger should go under the collar and place the box directly on your dog's vocal cords), IT WORKS like a through a Wonder! This collar stopped my 6 month old puppies annoying barking when I had clients in my home studio. This literally saved my business without harming my dog as it is NO SHOCK. In just 5 days he became a completely calm puppy. We love our dog more than anything and would never put a shock collar on him. We have tested the collar to ensure it will never shock. We tested the collar for its maximum "rebuke" by activating it 7 times (as if a dog would bark 7 times by repeatedly blowing into the test hole until the beeps and vibrations increased in intensity). .) We found the maximum beep and vibration rather annoying, but not painful at all, which we liked. After the 7th test, the device went into sleep mode for one minute. same - our pup is now happily sitting while we put a collar on him to wear during office hours without fuss) Also make sure you supervise your dog the first day he wears it - we had NO false alarms when we lowered the sensitivity to level 1 or 2 (the collar is set to level 4) but he beeped when he barked. That's what we wanted - no false alarms so he'd be happy to play, eat, drink and tug at his toys but only scold him when he barks loudly. Even now, just 5 days later without a collar, he doesn't bark at the cat or the clients that come into our home studio. What a blessing.
