The dog driving effect is not good in the following situations:
1. Your own dog, because it knows that the owner will not harm it, 2. Noisy environments, such as downtown areas or roadsides, 3, the dog with the owner outside----dogs know their owner will protect them, trained large dogs---- well-trained, 2. When the battery voltage is too low------the transmit power is low.
