It’s not all conditioning, the potential to snap is innate.
Good, careful owners, high quality training, sweet dogs. Andsometimes they go off. Like the family dogs who killed the two small children in Tennessee, savaged the mother when shelay over her babies. The ones in Canada who tore a quiet calm child out of his sister’s arms, people they knew very well. Conscientious owners who thought good training and good treatment would make good dogs.
I know its not ALL conditioning. I didnt say that.
Its a combination in many cases. But theres a reason why they pick these dogs to condition this way. Theres a genetic/breed component to factor in.
