Petco removes shock collars from sale

This week, those of us in the Force Free/Fear Free movement were given cause to celebrate when Petco, a major pet retailer in the USA, announced that it was removing shock collars from its stores and online platform.

Shock collars are aversives – they use pain to suppress an unwanted behavior. These totally unnecessary devices are inhumane when behavioral science has moved along to prove that positive reinforcement training works better and is an ethical approach to dog training.

I’m interested in this subject because, sadly, shock collars are widely available in New Zealand. I see many Facebook groups of dog owners who recommend these devices as soon as there is a barking dog complaint, for example. And the body language of a dog wearing a shock collar tells the story of a dog being punished.

To continue to raise awareness to this subject, I include the statement of the Pet Professional Guild released this week in response to Petco’s announcement.

Official PPG Statement

Official Pet Professional Guild Response to Petco’s Removal of Electric Shock Collars from Stores

The Pet Professional Guild (PPG) and The Shock-Free Coalition are greatly encouraged by Petco’s announcement on October 6, 2020 that it will no longer sell electric shock collars “operated by a person with a remote in hand.” PPG has always believed unequivocally that the pet-owning general public needs – and deserves – to have access to better educational tools so they can, 1) make the right decisions regarding their pets’ training, care and welfare, and 2) ensure they live in safe, nurturing and stable environments, free from fear and pain.

Scientific Data
Increasingly, peer reviewed, scientific studies are showing that, whether discussing dogs, humans, dolphins or elephants, shock as a form of training to teach or correct a behavior is ineffective at best and physically and psychologically damaging at worst (Schilder & van der Borg, 2004; Schalke, Stichnoth, Ott, & Jones-Baade, 2007; Polsky, 2000; Cooper, Cracknell, Hardiman, Wright & Mills, 2014). Overall (2013) states that shock collars, aka e-collars, “violate the principles of three of five freedoms that define adequate welfare for animals: Freedom from pain, injury, and disease, freedom to express normal behavior and freedom from fear and distress.”

The current scientific data, in addition to the moral and ethical concerns about mental and physical damage to animals subjected to methods using force, fear and/or pain, have moved a number of representing professional organizations* to advocate for the use of humane training techniques founded on evidence-based learning theories and avoid training methods or devices which employ coercion and force. PPG is delighted that Petco has now joined their ranks.

Effects of Electric Shock
The use and application of electric shock provides no effective strategy for an animal to learn a new or alternative behavior. Some common problems resulting from the use of electronic stimulation devices include, but are not limited to:

Infliction of Stress and Pain
Generalization
Escalation
Global Suppression or “Shut-Down”
Fear, Anxiety and Aggression
Redirected Aggression
Unintended Consequences

Shock-Free Coalition
In September 2017, the Pet Professional Guild (PPG) rolled out its Shock-Free Coalition, the key purpose of which is to build a strong and broad movement committed to eliminating electric shock devices from the worldwide supply and demand chain. This would be achieved by:

 Engaging and educating pet owners and shelter/rescue workers to help them make informed decisions about the management, care and training of the pets in their charge.

Building a worldwide coalition that provides pet owners access to competent, professional pet industry service providers.

Creating widespread pet industry transparency and compliance regarding how professionals implement their services and communicate their philosophy to pet owners.

Supporters are encouraged to sign the Shock-Free Pledge, much in the same way as Petco has invited supporters to sign its #StoptheShock petition.

Consumer Transparency
One of PPG’s key goals is to shape the pet industry to ensure that dog trainers, behavior consultants and professional pet care providers, 1) pursue an ethical responsibility to do no harm to the animals in their care, and 2) present their qualifications and experience truthfully with full transparency and disclosure – including the training tools and methods they use.

PPG recognizes that industry changes will happen in stages and, just like the progressive behavior change programs we create for the animals in our care, gradual changes must be reinforced. By encouraging “anyone using or looking for shock collars to consider training with treats instead of electricity and partnership instead of pain,” Petco has made an important first step towards improving the lives of pets everywhere, as well as educating dog owners about alternative, kinder training methods and tools. We look forward to seeing electric fence systems, which work in exactly the same way as shock collars, i.e. by causing fear and pain, follow suit.

Does training method matter?: Evidence for the negative impact of aversive-based methods on companion dog welfare

Your dog may be the apple of your eye, but let’s be honest: she is an animal, with her own instincts and idiosyncrasies, and there are going to be times when she makes you want to tear your hair out.

Much you want to, however, new research suggests that you should never yell at or otherwise punish a mischievous mutt.

According to a new study uploaded to pre-print server bioRxiv, aversive training such as positive punishment and negative reinforcement can have long-term negative effects on your dog’s mental state.

“Our results show that companion dogs trained using aversive-based methods experienced poorer welfare as compared to companion dogs trained using reward-based methods, at both the short- and the long-term level,” the researchers write in their paper.

“Specifically, dogs attending schools using aversive-based methods displayed more stress-related behaviours and body postures during training, higher elevations in cortisol levels after training, and were more ‘pessimistic’ in a cognitive bias task.”

This sort of research has been conducted before, and found that aversive training has negative effects, but it’s primarily been on police and laboratory dogs. In addition, the aversive training tends to be shock collar training, which is only one of several tools used.

So, led by biologist Ana Catarina Vieira de Castro of the Universidade do Porto in Portugal, the international team of researchers conducted their new study on companion dogs.

The animals were recruited from a number of training schools in Porto – 42 dogs from three schools that use reward-based training like food treats or play, and 50 dogs from four schools that use aversive-based training, such as yelling, physically manipulating the dog, or leash-jerking.

Each dog was filmed during the first 15 minutes of three training sessions, and saliva samples were taken to assess stress levels from training – three from each dog relaxing at home to establish baseline levels of stress hormone cortisol, and three from each dog after training.

The researchers also analysed the dogs’ behaviour during training to look for stress behaviours, such as yawning, lip-licking, paw-raising and yelping.

Unsurprisingly, the dogs in the aversive training classes showed elevated stress behaviours, particularly yawning and lip-licking. Their saliva also had significantly increased levels of cortisol compared to when they were relaxing at home.

By contrast, the positive reinforcement dogs were pretty chill – far fewer stress behaviours, and much more normal cortisol levels.

The next step was to assess the longer term effects of this stress. A month after the dogs were assessed at training, 79 of them were then trained to associate a bowl on one side of a room with a sausage snack. If the bowl was on that side, it always held a delicious treat; if located on the other side, the bowl never had the treat. (All bowls were rubbed with sausage to ensure the smell didn’t give the game away.)

Then, the researchers moved the bowls around the room to ambiguous locations to see how quickly the dogs would approach in search of the treat. Higher speed was interpreted to mean the dog was anticipating a mouthful of deliciousness, whereas a slower speed meant the dog was more pessimistic about the bowl’s contents.

Sure enough, the more aversive training a dog had received, the more slowly it approached the bowl. Interestingly, dogs from the reward-based training group actually learnt the bowl location task faster than the aversive-training dogs.

This suggests that reward-based training may actually be more effective, although the researchers suggest this may be because the dogs already understand treat-based training methods. It’s possible that the other group would learn more quickly were an aversive method applied – more research needs to be done to determine this.

Overall, though, the results seem to imply that aversive training doesn’t necessarily have an edge over reward training, and that reward training is much better for your dog’s happiness.

“Critically,” the researchers said, “our study points to the fact that the welfare of companion dogs trained with aversive-based methods appears to be at risk.”
