10. Aggression

Dog aggression is exhibited by growling, snarling, showing teeth, lunging and biting. It is important to know that any dog has the potential to become aggressive, regardless of breed or history. However, dogs with violent or abusive histories and those bred from dogs with aggressive tendencies are much more likely to exhibit aggressive behavior towards people or other dogs. Reasons for aggression are basically the same as the reasons a dog will bite or snap, but overall canine aggression is a much more serious problem. If your dog has aggressive tendencies, consult your vet first - it may stem from a health problem. Then, seek the help of an experienced dog trainer. Serious measures should be taken to keep others safe from aggressive dogs!
