Aggressive Australian Shepherd Puppy
We got our puppy when he was 13 weeks old. He (King) was very friendly to everybody that came to the house. One weekend we had a friends granddaughter come to visit and King started growling and barking at her when she entered the house. We had to put King in his kennel while the little girl was visiting.
After this weekend we noticed that King would not let the people that normally came to visit on our deck or out of their cars. He growls and show all of his teeth.
King is not our only dog. We have an 8 year old female Australian Shepherd that is very friendly.
