The Dogtra YS600 No Bark Collar offers the latest cutting edge technology with a highly accurate Accelerometer Bark Sensor. The Persistent Bark Indicator alerts dog owners of excessive barking each time the unit is turned off. The YS600 comes in a durable sleek design that is smaller and lighter than previous high powered no bark collars. 

The YS600 outputs low-high stimulation from 1-10 levels, which makes it easy to find the right stimulation for all breeds and temperaments, and features a non-stimulating High Performance Pager (HPP) vibration that has a more vibrant sensation than a traditional pager.  The YS600 is fully waterproof and equipped with plastic shielded 5/8" Enhanced Contact Points.
