Dog Repeller Ultrasonic with LED Effective for Dogs Anti-barking Training Device

The following situations are not effective in repelling dogs:

1, own dog, because it knows the owner will not hurt it;

2, Noisy environments, such as downtown areas or roadsides;

3, Dogs with their owners – dog fighting; trained large dogs – well-trained;

4, When the battery voltage is too low – low transmitting power.

Note: Usually it is best not to take the dog repeller to deliberately tease the dog, because the dog listens to it more and then it is not surprising.
