In this episode, Lisa sits down with Dr Nick Sneddon, Senior Lecturer in Animal Breeding and Genetics at Massey University, to unpack one of the most important yet misunderstood topics in the dog world: how genetics and early life experiences shape behaviour, health and lifelong wellbeing.

The episode also challenges popular trends in modern dog breeding and highlights why selecting for temperament, function and long-term welfare matters more than appearance or popularity.

In this episode, Lisa and Nick explore:
• What genetics really means for behaviour, temperament and health
• The balance between nature and nurture in shaping dogs
• Developmental programming and why early life experiences have lifelong effects
• What ethical breeding looks like when long-term welfare is prioritised
• The hidden connection between physical health, structure and behavioural outcomes
• Red flags in breeding practices that may increase anxiety, reactivity or poor coping skills
• What responsible breeders should measure beyond basic genetic testing
• Questions future puppy owners should be asking breeders before choosing a dog
• The future of dog welfare and how public decision-making influences the dogs we see in society

This episode is for dog owners, trainers, breeders and anyone curious about the deeper biological foundations of behaviour. If you’ve ever wondered why some dogs seem naturally resilient while others struggle despite great training, this conversation offers a powerful lens into how early life and genetics shape the dogs we live with today.
