For added protection, the collar stops working for one minute should your dog reach the seventh level.   How to Test   Place the test bulb over the bark collar    Blowing on the sensor, the device beeps  and then the test bulb brightens. Note: Proper fitting of the collar is important. A collar worn for too long or made too tight on the pet's neck may cause skin damage. These collars can cause pressure necrosis if used incorrectly and is often misidentified as burns. Avoid leaving the collar on the dog for more than 12 hours per day.   If it's possible, re-position the collar on the pet's neck every 1 to 2 hours. Wash the dog's neck area and the contacts of the collar weekly with a damp cloth. Examine the contact area daily for signs of a rash or a sore. If a rash or sore is found, discontinue use of the collar until the skin has healed.
