♦ At the first bark, this anti-bark collar will apply a short warning tone.If a second bark occurs within thirty seconds, a more intense tone is sounded.From the third bark, a more intense tone is sounded along with a short, mild shock.
♦ This pattern is repeated through 7 levels. The first 2 levels are only with progressively warning tone.If your dog continues to bark through the rest 5 levels, the more intense sound and shock apply after each bark until your pet stops for thirty seconds, then this anti-bark collar will automatically reset to the first"tone only"level of correction.
♦ To protect the dog, if the continuous stimulus reaches the 7 levels, then the collar will stop working for 1 minute.
♦ The use of the warning tone followed by increasingly intense tones and shocks sets up a pattern that your dog will quickly learn is caused by its own barking. ♦ Over time, the dog will learn their behavior triggers the tones & shocks, stopping them from barking.
♦ This no bark collar can be adjusted to control the sensitivity of the voice, according to the size of dogs barking.
