Research Studies and Articles

We understand how confusing and concerning raising your puppy and dog in today’s world. There is so much information to process and to understand what fact from inflated false nonsense is. We spent some time gathering the data that has helped inform us on how to proceed in the world of ensuring a safe and secure process in training as well as understanding who our pup is. We hope this information albeit can be confusing can help you create the best world for your canine companion along with keeping them safe! Please be aware that the information provided here only scratches the surface, and it’s essential to note that there are numerous other sources of data available on these subjects.

Disclaimer! Here are a few pointers to be aware of when reviewing the data.

  1. Context Awareness: Be mindful of the study’s context and limitations to avoid drawing broad conclusions.
  2. Methodological Considerations: Assess the research methods employed, understanding their potential impact on results.
  3. Sample Size Caution: A small sample size may limit the generalizability of findings; consider this when interpreting results.
  4. Correlation ≠ Causation: Be cautious about inferring causation solely based on observed correlations.
  5. Publication Source: Assess the credibility of the journal or source to ensure reliability.
  6. Biases and Confounding Factors: Be aware of potential biases or confounding variables that may influence the results.
  7. Temporal Relevance: Consider the age of the research; newer studies might reflect current trends or understanding.
  8. Industry Influence: Be wary of studies funded or influenced by industries that could benefit from specific outcomes.
  9. Peer Review Status: Check if the research has undergone peer review for quality assurance.
  10. Data Interpretation: Ensure accurate interpretation of statistical significance and relevance to real-world scenarios.

I only hope that the data presented inspires you to dig deeper and to question a trainer before trusting their methods.

Shock/Prong Collar Use

A quote by Dr Ian Dunbar:
To use shock as an effective dog training method you will need:|
• A thorough understanding of canine behavior.
• A thorough understanding of learning theory.
• Impeccable timing.
And if you have those three things, you don’t need a shock collar.”
