The ‘Progressive Correction’ will deliver beep first, then send static shock with increasing intensity to get your dog’s attention. Your dog suffers no harm even at the maximum shock intensity. In very extreme cases, the collar receiver would stop sending warning after 3 full correction cycles, to prevent injury to your dog from excessive stimulation.
