Handling Aggression Like a Loaded Gun: The Dangerous Consequences of Unqualified Dog Trainers

Feb 17 / Teresa Tyler

The issue of unqualified trainers and behaviourists working with aggressive dogs is a pressing concern, with far-reaching consequences for public safety, animal welfare, and the field of canine behaviour itself. While the increasing interest in dog training and behaviour modification has brought about a wealth of new perspectives and techniques, it has also led to an influx of self-proclaimed experts who lack the necessary education, experience, and ethical grounding to handle complex cases, particularly those involving aggression.

Aggressive behaviour in dogs is a multifaceted issue that can be influenced by genetics, environment, past experiences, and underlying medical conditions. Addressing aggression requires a deep understanding of canine ethology, behavioural science, and appropriate intervention strategies. However, many individuals offering training and behavioural services lack formal education in these areas. Instead, they rely on anecdotal experience, outdated dominance-based methods, or poorly understood interpretations of canine behaviour, often exacerbating the very issues they claim to resolve.
One of the most concerning aspects of unqualified intervention is the potential for escalation. Aggressive behaviours that are not properly managed—or worse, are suppressed through inappropriate punishment—can become more unpredictable and severe. Dogs that are subjected to aversive techniques, such as harsh corrections, intimidation, or physical force, may suppress their warning signals, leading to situations where aggression emerges suddenly and without the usual precursors. This not only places owners and the wider public at risk but also significantly increases the likelihood of euthanasia due to perceived unpredictability and danger.
The misuse of training tools and techniques by unqualified individuals can have lasting negative effects on a dog's psychological well-being (Wise, 2022; Guilherme-Fernandes et al., 2017; Ziv, 2017). Electronic collars, prong collars, and other aversive devices are frequently employed by those who lack the knowledge or willingness to implement evidence-based, humane interventions. The fallout from such methods extends beyond the individual dog, influencing broader public perceptions of dog training and perpetuating the misguided belief that aggression must be met with dominance and control rather than understanding and rehabilitation.

Handing an aggressive dog to an unqualified trainer is akin to giving a loaded shotgun to a toddler—it’s dangerous, unpredictable, and
potentially catastrophic.

Guardians seeking help for their dogs are often in a vulnerable position, desperate for solutions and willing to place their trust in anyone claiming expertise. This creates an environment in which misinformation spreads easily, particularly in the digital age, where social media and online platforms provide an unregulated space for self-taught individuals to present themselves as ‘professionals’. The lack of standardisation and regulation in the dog training industry exacerbates this problem, leaving the responsibility to guardians to discern between credible professionals and those who operate without sufficient knowledge or ethical integrity.
The consequences of unqualified trainers working with aggressive dogs extend beyond the immediate risk of injury or harm. They contribute to a broader cycle of misunderstanding, fear, and ultimately, failed interventions that result in rehoming, abandonment, or euthanasia.
The damage is not limited to the dogs and their owners but also affects the credibility of qualified professionals, as the fallout from poorly handled cases can lead to distrust in the field as a whole. Addressing this issue requires a shift towards greater regulation, education, and public awareness. Without more trainers and behaviourists signing up to clear professional standards and accountability, the welfare of dogs and the safety of the public remain at risk. Guardians must be encouraged to seek trainers and behaviourists with accredited qualifications, verifiable experience, and a commitment to ethical, evidence-based practices. Only through such measures can the industry move towards a future where dog aggression is managed responsibly, reducing harm and ensuring better outcomes for dogs and the people who live with them.
