E - COLLAR TRAINING
The e - collar is a tool that will not need to be used in the mid to long term. It is a tool that is used to the minimum by using either or a combination of tone, vibration and stimulation. It is not a tool to punish a dog.
Without the correct training by an experienced e - collar trainer, a dog will be mentally damaged, develop fear, helplessness, escapism - run away, become aggressive and/or a combination that can be irreversible.
If your thinking about using an e-collar, get a professional to show you how to use it safely and effectively o the benefit of the dog. Quality e-collars are only used for the training and are supplied.
