Fear Aggression, This can be from
not properly socializing your puppy. Dogs like people often fear the
unknown.
Animal Aggression - Because a dog
is animal aggressive does NOT mean that dog will be aggressive towards
a person! These are 2 entirely different forms of aggression.
Territorial Aggression, Again
early socialization is key along with your status of alpha. If you are
alpha, they should not feel the need to protect their territory from everyone!
Possession Aggression, this can be
food, bed, toys, treats, or even people. This is another thing
that can be reduced by early training and socializtion. The
enforcment of you being the alpha will reduce them as seeing you as
possession. When they are puppies it's important for you to take
their toys while playing and reward them for not arguing. When
feeding puppies, take some kibble and feed from your hand.
Redirected Aggression, this is a
hard one to pinpoint and it takes alot of work and paitence to correct.
Example, you have 2 dogs in the back yard, another dog walks by the fence and
your dogs start growling and barking at the 3rd dog. One of the 2 dogs
can get so hyped up from the 3rd dogs presence that it turns on your other
dog.
Maternal Aggression. The need to protect their
puppies.
Dominance Aggression, Canines live in a
pack with a hierarchal system. You as the owner must be the Alpha at all
times. There are ways to re-enforce this status on a daily or as needed
basis. Understanding canine behavior can help with this form of
aggression. For instance, staring at a dog can be considered a
challange. you should never maintain eye contact with an unknown dog.
