The puppy showed several different types of aggression, including food aggression. To be honest, I was crying too hard to watch the temperament test closely.

I know in one of Sue Sternberg's videos, they show several aggressive puppies who are under 3 months old. They were just born like that, it was not due to the owner. Sue Sternberg is a nationally respected behaviorist who specializes in aggression. If a puppy is born with aggression issues, you can't reverse it too easily. Most likely there's a screw loose somewhere and the problems will only worsen as the dog grows.
