MarkandCraigContain-A-Pet’s trainers recommend the settings to be set so that the collar tonesand corrects at the same time.  These are sound pet behavior principles that will save you worry, save you money and more importantly, possibly save your pet’s life!

Look at it like this.  Your conditioned pet knows her boundaries by her sense of smell and repetition.  If you provide a warning each time, you are teaching your pet to test the boundaries.  Each time she tests the boundaries, she may get corrected … and it’s not her fault!.  In addition, she is also draining the batteries in the electronic receiver collar.  One day there will be no tone, she can keep going … right on out of the yard!
