Many dog owners resort to punishment out of frustration, misinformation, or outdated training advice. While punishment in dog training might temporarily suppress unwanted behaviours, it often leads to unintended consequences like fear, anxiety, and increased aggression. Science has shown that punishment-based training methods can cause more harm than good. So what actually works? Let’s explore why punishment is ineffective and what you can do instead to help your dog learn in a way that builds confidence, trust, and long-term success.

The science of learning: Why punishment isn’t effective

Understanding operant conditioning
Dogs learn through association, and operant conditioning explains how behaviours are strengthened or weakened. While punishment (both positive and negative) aims to decrease behaviour, research has consistently shown that it does not effectively teach the dog what to do — only what not to do.

The fallout of punishment
Studies have found that punishment can lead to:

• Increased stress and fear.
• Suppression of behaviour rather than real learning.
• Erosion of trust between dog and handler.

Scientific evidence
A study by Vieira de Castro et al. (2020) found that dogs trained using aversive methods exhibited higher stress levels compared to those trained with reward-based methods. Similarly, research by Rooney & Cowan (2011) indicated that high levels of punishment may have adverse effects on learning and increase anxiety-related behaviours.

The unintended consequences of punishment

Escalation of aggression
Punishment can create fear and frustration in dogs, which may lead to defensive aggression. When a dog is punished for growling, for example, they may suppress that warning signal but still feel threatened—which increases the risk of biting without warning.

Unclear associations
For punishment to be effective, it must be immediate and precise, which is difficult for most owners to achieve. If there is even a slight delay, the dog may not associate the punishment with their action, leading to confusion and stress.

Suppressed warning signals
Dogs communicate discomfort through body language and vocalizations. When punishment suppresses these signals (e.g., growling or avoidance), it can result in sudden, unanticipated aggression since the dog no longer feels safe expressing discomfort in lower-intensity ways.

Scientific evidence
Fernandes et al. (2017) reviewed multiple studies and concluded that aversive training methods compromised dog welfare, increasing fear-based and stress-related behaviours.

What works instead: Reinforcement-based alternatives

Rather than focusing on stopping unwanted behaviours through punishment, effective training teaches dogs what we do want them to do.

Teach an alternative behaviour
If a dog jumps up to greet people, instead of punishing the jumping, train them to sit for greetings. This way, they learn an appropriate behaviour that gets rewarded.

Management and prevention
Set your dog up for success by controlling their environment. For example, if your dog tends to chew furniture when left alone, provide appropriate chew toys and limit access to off-limits areas.

Reward-based training
Positive reinforcement strengthens desired behaviours, making them more likely to be repeated. Dogs trained with rewards are more engaged, eager to learn, and have better long-term behavioural outcomes.

A better way forward

Punishment in dog training is not only ineffective but also risks damaging your relationship with your dog. Positive reinforcement-based training is scientifically proven to be more effective, humane, and beneficial for long-term learning.
