Hi Could someone just clear something up for me please. Reading some other threads I am now a bit confused about biting. On one thread a vet had said that going for the face and head showed an intent to kill (this was on a human). In another thread that had a link to some text about measuring aggression and how you tell if it is serious intent on not it mentioned if a dog confines it's attention on the head area it does not mean to cause seriousl harm. On this one it was talking about dog/dog aggression. Is one right and the other wrong or does it depend on whether the aggression is towards humans or dogs?
