American Pit bull Terrier
Originally bred to be aggressive fighting dogs so they have that instinct hardwired in them. If they bite, they tend to go for the throat and not any other body part. They’re all about dominance so shouldn’t be around kids.
Daschund
Daschund better known as sausage dogs tend to be aggressive and very possessive. They don’t have much patience for small children if they’re manhandled. They like to be pack leaders so they can bite kids trying to discipline them.
