Dogline minus ion dog collars provide a healthy ion climate. Minus ions (anions) are charged particles that occur in high concentrations mainly in forests, mountains and waterfalls. This natural, relaxing environment has a positive energizing effect not only on people but also on your dog. There is also a pleasant side effect: ticks and other parasites do not like minus ions. In Asia from the daily life can no longer be imagined, the minus ions (anions) technology was now packed by a special material mix in the DogLine dog collar made of silicone.
