What is a common mistake when using a training collar on a dog?

Placing a training collar too low on the neck is a common mistake because it can lead to discomfort and ineffective training. The collar should be positioned high on the dog's neck, just below the jawline, where it can provide the most control and response. When the collar is placed too low, it may not effectively stimulate the intended area, reducing the collar's effectiveness during training. This improper placement can also increase the risk of injury to sensitive areas or lead to an improper fit, which can result in the collar slipping off or causing irritation. Proper placement is essential for both the safety of the dog and the success of the training protocol, as it ensures the collar functions as intended without causing harm.
