When should you NOT use a remote trainer?
If your dog has a medical condition, such as a heart problem, it is essential that you seek the advice from your veterinary specialist, before starting any training with the active collar.
If your dog is of a nervous disposition be sure to check the effect of the stimulation while the dog is on a secure line or in a safe area. Training should cease if there are any signs of trauma.
Do not use a remote trainer on your dog less than six months of age for any reason. Never use it on a dog younger than about ten months old for obedience training, since he must first understand completely the command that you give, before you make any attempt to correct him using the stimulus.
