You are the shepherd, not the engineer of your dog's behaviour.
Any individual is a mosaic of their extended family.
Panos & Luke discuss the roles genetics and environment (innate and learnt behaviour) play in what creates a behaviour, temperament and mindset.
Environment brings forth genetic expression and it's potential, this relates to type/level of drive, temperament, health, social behaviours, anxiety and aggression to name a few.
It's not only training that develops a behaviour, it is also the DNA of your dog.
