Protect your dog from bugs naturally without the use of chemicals (poisons), sprays or lotions using 0bug zone tags. Chemical-free, eco-friendly, effective solution uses kinetic energy to create a natural frequency barrier that helps protect from targeted insects for up to 3 months. Waterproof, works even if it gets wet. Non-toxic and odor free. Safe for all weights and ages. Helps protect dogs from fleas and ticks. According to research, each insect is repelled by a specific frequency. The frequency is encoded into the magnetic strip on the 0bug zone. The natural energy field created by the dog expands the specific frequency which creates a barrier from insects. 0Bug zone tags do not interfere with any treatment modalities that your dog may have undergone no ill effects or side effects of any kind for 0bug zone users.
