Why & How to train your dog?

1)Many times, dog barking is to attract the owner's attention and response. Beat or swearing will cause counter-effects. The Colohas dog ultrasonic trainer is a good choice to control barking in a gentle manner.

2)Once the dog barks, the pet owner should 'disregard' his loud barking and use barking control device to attract the dog’s attention and disrupt his current state of mind.

3)Waiting for your dog to calm down, you can give the dog a reward to reinforce his memory, such as snacks, love petting, etc. Consistent training is required to achieve effective and long-term result.
