Electronic training involves the use of an electric shock as an aversive. Common forms are collars which can be triggered remotely, or that are triggered by barking, fencing that delivers a shock when a dog wearing a special collar crosses a buried wire, and mats that can be placed on furniture to deliver a shock. Some aids deliver an aversive such as a spray of citronella when triggered. The use of electric shock aversives for training dogs is the subject of considerable controversy. Supporters claim that the use of electronic devices allows training at a distance and the potential to eliminate self-rewarding behaviour, and point out that properly used, they have less risk of stress and injury than mechanical devices, such as choke chains. Opponents cite the risks of physical and psychological trauma associated with incorrect or abusive use.
If your puppy is not sleeping in her crate or pen, and is out in the house, you must follow her around to know what she is doing: chewing a bone, running circles, getting a drink of water, etc. In fact, don't take your eye off of her! If you cannot watch her continuously, you must put her back into her pen or crate to prevent potty training "mistakes".
Puppies would much rather play with leaves and bugs than go potty, if you aren’t there to see that you won’t know your pup needs to go back into his crate and come out again 5-10 minutes later! He will learn to sneak away, and have accidents inside. If you leave him outside for an extended period of time, chances are when you bring him back in he will need to go outside again soon or have an accident.
A training class is not there to train your dog. Its purpose is to teach you to train your dog so you will need to be committed to train your dog for short sessions (5 minutes) several times a day rather than just simply turn up for classes! This little bit of training everyday will be repaid with a lifetime of living with a well behaved dog. You will also learn to avoid problems before they begin as well as receive help to overcome any that you already have with your dog.
