>>I seriously doubt this was about prey.<<
I didn’t say it was the motivation, I said dogs are prey animals. Their instinct is to clamp and shake.
I think your mistaking prey for predator...a dog is a predator animal. Prey is what they kill and eat. Wolf= predator, deer=prey....
No, prey instinct is to either run from a predator OR (if circumstances warrant) fight the predator.
Predator instinct is to go for the throat and kill the prey.
