Everything You Need to Know About Dog Shock Collar
What Exactly Is a Dog Shock Collar?
The training tool that is commonly known as a shock collar, remote training collar, electric dog collar or e-collar, can do much more than shock. When used as part of a positive training regiment, the shock will never be used except as an emergency measure.
Remote training collars have a tone or beep which can be tied to positive reinforcement to enforce recalls or other desirable behavior. Training collars also have a vibration which gets the dog’s attention without any pain. Some shock collars have variable settings for the vibration as well as the shock.
Who Should Use a Shock Collar?
Whether you are a first-time dog owner worried about keeping your dog safe, an experienced dog owner who wants to push the limits of obedience, hunting, or canine sports, are you are a trainer working with clients’ dogs on problem behavior, a remote training collar can be a useful tool for you.
A remote training collar communicates to your dog no matter where she is. By tying tone or vibration to a reward, you can continuously tell your dog when she is doing the right thing. If you tie the tone to a behavior like coming back to you, you can feel confident that whenever you press the tone your dog will return to you. The consistent tone is similar to a clicker, but unlike a clicker it can go with your dog and provide the same stimulus continuously. Vibration can be more effective than a tone at getting a dog’s attention. Vibration is great for deaf dogs as well.
While we hope you will never need to use the shock feature on your dog, if your dog is running towards traffic or about to attack another dog or person, a shock is much better than the alternative. It is your responsibility as a dog handler to keep your dog out of situations in which a shock would be necessary, and you should never trust that the shock will be effective. A very determined dog or a dog who is in extremely high drive mode can block out even an intense shock.
That said, a dog that likes to joy run out the front door or just can’t contain herself at the sight of another canine can be stopped from running into the road effectively by a shock if other containment measures and training fails.
Hunters have long struggled to train their dogs to stay near and return to them when called, as well as to remotely listen to commands to help them find the game. Remote training collars can help hunters communicate with their dogs remotely to zero in on game. Furthermore, if a hunting dog in training should be unexpectedly distracted by a distraction like a rabbit or deer running by, the shock feature can keep the hunting dog from running off and becoming lost.
Hunters can benefit from using a GPS collar as well, in case they lose track of their dogs despite the remote training collar. The GPS collar can allow you to find your dog no matter where she runs to.
How Does A Shock Collar Work?
Shock is delivered by two prongs, either metal or metal coated with silicone. Quality shock collars offer a wide range of shock. The lowest setting should be barely felt by even a small dog, while the highest setting is more than most people can handle. ALWAYS use any measure of shock on yourself before even thinking about using it on your dog. Don’t use the shock except in an emergency situation, as it will hurt the relationship that you have with your dog and may also condition her to ignore the shock, requiring higher and higher levels.
The shock that is delivered is static electricity. The lowest setting is a twinge less than the shock from touching a car door with static energy, while the highest settings create a sharp shock that will make most dogs forget about anything but the shock. You can choose and adjust the shock level using the remote, then stimulate a momentary or continuous shock.
Vibration is provided by another feature within the collar that causes the unit to vibrate when triggered. Some collars have adjustable vibration while others provide a single level of vibration.
The tone is produced by a speaker within the collar receiver. Some collars have more than one tone, but most have only one clear, attention getting note.
Some collars feature light. The light flashes out from a generally LED light within the collar receiver when the button is pushed.
How to Use Dog Shock Collars
There are many uses for remote collars. Many owners keep remote collars on their dogs whenever the dog is awake or every time they leave the house with the dog. The shock collar can serve to communicate with the dog easily. Remember that a lead should never be attached to the collar, as the collar is not designed for this.
A beep can signal a positive behavior which you can then reinforce with treats, toys, or affection. A vibration can warn a dog that her behavior is not desirable. If the dog refuses to stop and is entering a dangerous situation and you can’t interfere with the behavior you can use a shock correction as an emergency measure.
Shock collars are also used for dogs that need to be off leash to perform a function like hunting. Dogs that are generally good off-leash but have triggers like prey-drive or want to meet other dogs can be stopped from running into traffic or other dangers by a shock collar.
- To keep your dog from running away. If your dog is an escape artist, slipping out from between guests’ legs or jumping fences, you can use the vibration to warn and the shock to stop your dog from running away into potential danger.
- To control your dog if you lose control. If your dog has high prey drive or aggression towards people or other dogs, you can use the beep to condition positive behavior and the shock in case you lose control, to break up a fight or stop your dog’s progress towards the object of aggression. Keep in mind that a dog in the “red zone”, or in very intense drive may ignore the shock or it may even elevate aggression. It is advised that you work with a trainer or animal behaviorist when working with aggressive dogs.
- For hunting. Hunters have always struggled to train dogs remotely, especially since hunting dogs so often have high energy and drive. A remote collar serves as continuous communication and an emergency measure in case the dog takes off.
Pros of Shock Collars
- Consistent beep coming from the same place on the dog’s neck ties strongly to reward with training. A strong tie between stimulus and reward is important to get dogs to respond to the stimulus even under distractions, so this consistent stimulus is very useful and can be more effective than a clicker.
- Vibration startles dogs. If you are having trouble getting your dog’s attention, you don’t have to resort to shock. The vibration is an effective way to startle dogs and get their attention when they would rather ignore you.
- Shock can stop dogs that are running into danger or will become a danger to others. A shock can be a highly effective emergency measure to stop dogs in mid-run that otherwise would be impossible to stop.
Cons of Shock Collars
- Can damage the bond between dog and handler, especially if used incorrectly. If you think that because you are behind your dog or out of sight when you shock her she won’t know you did it, you can think again. Your dog will quickly come to understand that you are the one shocking her, which can hurt the relationship between you.
- May cause physical harm. Some dogs experience rawness and redness around the contact points, especially when shocked strongly or repeatedly.
- Makes training dependent on technology. Some dogs will realize that they only get shocked when the collar is on and ignore commands without it. Some dogs won’t perform without the collar beep to cue the coming reward, even with a lot of training.
- Higher range collars can be expensive. Especially compared to the alternative training technique: a long line, this can be an expensive tool. A GPS collar for safety will cost even more.
Are Dog Shock Collars Dangerous?
There is a lot of stigma attached to shock collars for good reason. Shocking your dog for undesirable behavior is not part of a positive training program. A shock can result in a reduction of the trust that your dog has for you and may cause anxiety or aggression.
Causing physical pain to your dog either by striking her with your hand or delivering a shock has similar undesirable psychological consequences on the dog and the owner. Furthermore, this kind of training has been proven to be less effective than positives, relational training techniques.
The shock delivered by the collar is designed to be harmless to your dog, but repeated uses or extended shocks at high voltage can damage the skin on your dog’s neck. Some dogs that suffer from preexisting sensitivities, heart conditions, or neurologic conditions can have aggravations to their conditions as a result of even mild shocks, so check with your veterinarian before using the shock with your dog. The beep and vibration, on the other hand, are generally safe.
Does Shocking With a Remote Training Collar Hurt Your Dog?
At the mildest setting, shock collars are not painful, but the higher settings can be very painful. If you are considering using a shock collar on your dog, use it on yourself first in increasingly higher settings. Make sure that you know exactly what you are doing to your dog.
Dogs trained using aversive techniques may not be as trusting of their handlers or as reliable in their performance, besides being stressed. Use the shock only as a last resort in emergencies, and rely on positive conditioning using the beep and vibration.
Are Shock Collars Effective for Aggressive Dogs?
While remote training collars used in the beep or vibration setting can be very good at reconditioning aggressive dogs and getting their attention, using the shock setting will have an undesired effect. If you are working with an aggressive dog, don’t ever rely on the shock feature to stop your dog or use it to punish your dog.
Should I Use a Shock Collar to Train My Dog?
If you are following a positive training protocol with your dog and are considering adding a remote training collar to your training regiment, there are some very good reasons to make the leap.
If your dog has a hard time responding to you at a distance or when there are a lot of distractions, the consistent tone tied to a reward can get her attention and bring about the desired behavior. Vibration can surprise your dog out of inappropriate behavior.
If you are confident that you have a positive training protocol that will work with your dog using a remote collar and plan to only use the shock for an emergency, the remote collar might be a great choice to train your dog.
How to Train a Dog with a Shock Collar
A shock collar is generally thought of as being an adverse training tool, but there are many ways to use it positively. Read these tips for training using a shock collar.
How to Use Shock Collar to Stop Dog Jumping
Does your dog jump on guests when they come to your home or when taking walks? Puppies express their joy and love with people by jumping, and it can be hard to overcome this as they get older. It isn’t necessary to use a shock to prevent your dog from jumping on you or other people. Tie the sound of the beep to sitting for a treat, favorite toy, or affection. When you think your dog is about to jump, beep. When she sits, have your guest greet her or reward her with a treat or toy.
How to Use Shock Collar to Stop Dog Barking
Barking is about as normal as it gets for a dog, and yet it is one of the most complained about behaviors when dogs are surrendered to animal shelters. Use a shock collar to stop barking by vibrating to distract from barking, then rewarding the resulting silence.
How to Use Shock Collar to Stop Dog Fighting
Fighting between dogs within a household is not uncommon, but it can be very stressful and potentially dangerous for both the dogs and people in the house. A remote training collar can be helpful to prevent fighting if used by a watchful handler. The trick is to trigger the vibration at the instant that you see tension between the dogs. This will break the dogs’ focus, at which point you can call them and reward for calm behavior.
How to Use Shock Collar to Stop Dog Digging
If your dog does things you don’t like when you’re not looking, like digging in the yard, you can trick her into thinking that you can see her all of the time. Teach your dog to come for a reward when she hears the beep, then watch through a window and ask your dog to come whenever she digs in the wrong place. Soon she will learn to only dig in a designated place. It is wise to provide somewhere for your dog to dig, since so many dogs love this activity.
How to Use Shock Collar to Stop Dog Whining
Dogs that whine or bark continuously can annoy you, your family, and your neighbors. Dogs that whine are often bored or nervous. Tie a beep to a great puzzle game or food toy, then gradually stretch out the time that your dog has to wait between beep and puzzle until a beep will quiet her for some time before the reward.
How to Use Shock Collar to Stop Dog Running away or Dog Chasing Cat
One of the most common uses of a shock collar is to prevent dogs from running away or giving into prey drive by chasing a cat or going after a squirrel. This is one of the few instances in which a shock is a reasonable training measure since a dog running away can put himself into serious danger. Train a recall by tying the beep to a treat and use long line training before progressing to off leash. Don’t test your dog in dangerous situations like near a road. If your dog gets away from you or takes off and doesn’t respond to the beep or repeated beeps, use a quick burst and then extended shock to arrest her motion.
A remote dog shock collar can be a very useful training and safety tool for your dog if used properly. Most dogs should never require you to use the shock function, but if you need to stop a dog who is running towards traffic or taking off after the neighbor’s cat, a shock collar could save your dog’s life.
