This aversion to pain, although the shock is slight are will not cause physical harm, it does get the dog's attention that it is doing something unwanted. They are most often used for barking, confinement or general behavior and each dog training collar is designed with each different behavior in mind. Over a short time, once the animal learns where the boundary is located, users can generally turn off power to the fence and even turn off the dog training collar. This type of dog training collar can also be used for other behaviors, such as digging in the yard or jumping up on neighbors or guests.A dog's behavior can be modified by many methods, but the three tools most often used are a dog training collar. For example, for barking, a small box built into the collar will give the animal a slight shock when it barks. As long as the dog feels the collar the typically will not cross the boundary line, having learned where the invisible line is located. Another dog training collar is equipped with a remote control that sends out a signal to the collar to jolt the animal whenever behavior does meet the owner's expectation. Similarly, confinement training with an invisible fence, will give the animal a shock electric bike once it passes a certain boundary in the yard. The owner should never use the remote for 'fun' or allow children access to the remote as inconsistent use, or unnecessary use can cause the dog to misbehave and even rebel against the user of the collar. It does not take long for the dog to realize that when they do not bark, they do not get shocked. When the animal begin unacceptable behaviors, the light shock can cause them to stop. Off-Site Behavior Modification Methods dog training collar There may be reasons when an invisible fence is not possible, such as living in an apartment or and electrical connection is not available for the fence. For example, if you take the dog for a walk without a leash and the dog is to stay within certain confines, whenever it strays from the area a push on the remote control sends out a light shock to bring the dog back into the desired area. When the fence is buried, many people place flags in the ground marking the boundary helping the dog to recognize the invisible line that when crossed will result in an electric shock. The dog training collar is placed on the dog and a wire buried underground emits low-level electricity much like an above-ground electric fence used for cattle.
