What’s Going On?

Last week, Petco announced they would be removing human operated shock collars from their stores!

This is a huge win for positive dog training, and also an amazing win for pet owners who can now see more effective training items on their local PetCo’s shelves.


Time to party!

What does that mean?

So far, it means that shock collars that have a remote control for the human will no longer be available for purchase in Petco stores.

Shock collars associated with underground and radio fences will remain, as will prong and choke collars. However, the FAQ for the recent announcement did say that Petco would be reviewing other items in the store, so I (and all the other positive trainers out there) are hopeful that these will also be removed soon.

So What’s the Big Deal?

The Big Deal is that a nationwide chain has announced its support for positive reinforcement-based training!

AND, they based that support on research showing that shock collars are 1) no more effective than positive training; 2) training with shock can have unintended side-effects, both mental and physical; and that 3) if there’s a kinder way to do something, then we should!

Now, I’m not saying they based their decision on this exact paper, but a recent study called “Efficacy of Dog Training with and without Remote Electronic Collars vs. a Focus on Positive Reinforcement” is a modern study that directly compares shock collars to positive reinforcement training.

The study compared three sets of dogs trained with different methods—Group 1 used professional trainers selected by electric collar manufacturers and shock collars, Group 2 used the same trainers as Group 1, but with balanced or traditional methods (usually a mix of punishment and minimal reward), and Group 3 used professional positive reinforcement-based trainers. All three groups taught the cues “sit” and “come.” The group trained with positive reinforcement alone performed better after training than either of the other two groups!

This study demonstrated that punishment, and in particular shock collars, isn’t needed for better responses to cues.

It also showed that “come” or the recall can be taught without punishment. Many shock collar trainers advocate for its use here in particular, saying a reliable off-leash recall is impossible without the collar. However, this study (and hundreds of positive trainers worldwide) demonstrate otherwise. Many of us (positive trainers) have trained awesome recall in the dogs we’ve worked with.

Side Effects?

Additionally, several studies show that punishment-based training, which includes training with shock, can have unintended side-effects such as stress, suffering, fearfulness, increased behavior problems (in particular aggression to dogs and humans), increased excitability, and distracted behavior. All of the side effects of punishment-based training can last for some time, even with positive training intervention.

A number of studies show that shock is a cause for aggressive behavior in a large number of animals. In dogs, electric shock has caused dogs to attack snakes they were being trained to avoid (via shock), and a variety of case studies showed evidence of increased aggressive behaviors when shock was used on dogs that showed signs of fear or defensive aggressive behavior at the sight of other dogs.

A Thorn by Any Other Name…

You’ll notice I’ve called shock collars “shock collars” throughout this article. However, there are many names this kind of collar goes by including:

  • stim collar
  • e-collar
  • electric collar
  • e-stim collar

But don’t be fooled. They’re all the same thing and work through the same method—delivering a pulse of static electricity to the throat of the dog that causes pain. And yes, it causes pain because otherwise, it wouldn’t do anything to change behavior.

Be Kind

“I did then what I knew how to do. Now that I know better, I do better.” ~Maya Angelou

I’ve always loved this quote, and I think it can apply to us and our approach to training animals. People who use different training methods aren’t bad people, but there are kinder and more effective ways to train our animals, so why wouldn’t we choose those?

Not only that, but if there’s a kinder way, don’t you think we should use it? It is so much easier to separate your emotions from your training with positive reinforcement. Think about it—if your dog ran away from you into traffic, what would you do when you got them back safe and sound?

Often when humans are upset, we punish the cause—in this case, the dog. How many of us have lectured or even yelled at our dogs when they returned to us after running off? How many would be tempted to hit the button on a shock collar remote to “punish” that behavior when, in fact, the time for punishment is long gone?

To the Future!

We don’t use leeches for general medical purposes anymore for a reason—science and research have developed better, more effective ways to treat people! The same goes for dog training—not only is science currently finding that positive training is more effective, longer-lasting, and easier to implement, so far it has also found that there are no negative side effects.

This is a good example of why continuing education (and education at all) is just as, or even more, important than “experience.” We are learning all the time, and we do ourselves, our pets, and our clients a disservice when we cling to “the old ways.”

I think this also highlights what Petco is doing. They recently learned that there were kinder, more effective training methods and chose to remove the most aversive tool from their inventory.

What Now?

Now, we can hope that other big chains follow Petco’s lead.

But that’s not all!

We can also advocate for our pets!

How Can I Help?

If this is important to you, please contact stores like PetSmart, Pet Supplies Plus, etc. and tell them how awesome Petco’s decision was and that you’d love for them to follow suit.

Also, please contact Petco and tell them you appreciate their decision (aka—Click and treat them with the reward of your praise and admiration!). Our pets aren’t the only ones who benefit from positive-reinforcement!

If you’d like an idea of what to say, try this:


Dear [store name],

Our pets deserve kind and humane training methods [like you recommend in your store (include this part if they have positive training in their stores)], and I think you should spread that message through your entire store by removing products like shock, prong, and choke collars and other items that work by causing pain, fear, or force from your shelves.

I’m sure you heard about Petco’s recent decision to remove shock collars from their stores. I’m so happy about this change, and I want to celebrate you too! Please consider a similar move!


[Your name]


If you’re writing to your favorite pet store, be sure to include what you love about them in your letter too! It’s always nice to get a genuine pat on the back, and sometimes it makes people more open to considering your request.

And don’t forget to make it positive!

There’s no need to tell store employees that they’re horrible for selling these products, etc. Most of the time 1) it’s totally out of their hands and decided at the corporate level, and 2) very few pet store employees are also professional dog trainers and likely won’t understand what you’re talking about if you approach it that way. (This isn’t to say that they donl’t know what they’re doing at all!—Just that they may not be aware of the science behind all the tools they sell.)
