When applying a training collar to a dog, how should the loose end be positioned?

The loose end of a training collar should be positioned over the back at the top of the dog's neck to ensure that the collar functions effectively and safely. This positioning prevents the collar from slipping and ensures that it exerts even pressure around the dog's neck when needed. Moreover, placing the loose end over the back helps to optimize the corrective aspect of the collar during training sessions, allowing for better communication between the handler and the dog. It also aids in preventing the collar from coming loose or becoming tangled, which could cause discomfort or injury to the dog. Thus, positioning the loose end in this manner enhances training effectiveness and keeps the dog comfortable and safe during the training.
