To ensure effective training and dog's safety, you must properly fit the collar on your dog. The collar must fit snugly to allow “contact points” to have a direct contact with the skin. Position the receiver unit high up on your dog's neck just below the ears.
You should be able to fit two fingers between the collar strap and your dog's skin. Too tight poses the risk of skin irritation and discomfort. Too loose and the contact points will not be able to administer the stimulation reliably and can cause skin irritation due to chafing. Cover the contact points with conductive rubber caps to reduce the risk of skin irritation or injury.
CAUTION: E-collars are not designed to be worn constantly. We recommend using the e-collar only under adult supervision and for no longer than 4 hours per day. NEVER attach a leash to an e-collar. Use a separate regular collar if there is a need for a leash.
It is highly recommended to limit the continuous shock delivery to no more than 3 seconds (the smaller the dog the shorter it should be).
