The following situations may result in reduced effectiveness of the dog repellent: 1. Dogs kept alone, knowing their owners won't harm them; 2. Noisy environments, such as city centers or roadsides; 3. Dogs with their owners: their effectiveness depends on the device's power; large, well-trained dogs: they are well-trained; 4. Low battery voltage: low emission power. The above situations do not affect the effectiveness of this product, as dogs kept alone, dogs that go out frequently, dogs with their owners, and well-trained dogs will not bite. Note: It is best not to deliberately tease dogs with the repellent, as they will become accustomed to hearing it constantly. Recharge the device immediately when the light dims noticeably in repellent mode.
