I am not an expert so I could be blowing smoke. I have seen this behavior discussed in a couple of dog TV shows. Kelsey is demonstrating behaviors of an alpha dog. She is trying to protect you from others and the chore is so overwhelming to her, because she is so small and the world is so big. Because she feels she must protect you and her "den" the burden is making her anxious and this is leaking out in other areas of your life.
I definitely agree that a professional is warranted. You and your wife's actions, in the past and present (although unconscience) has actually contributed or created this situation. You will need an objective person to observe how you treat kelsey in everyday life and determine what actions you and your wife are doing that has elevated Kelsey to Alpha status.
Once she is in her proper place in the pack, the overwhelming burden will be removed and she will become more relaxed and take her cues from you, so that when strangers or children enter the picture, she will not be so aggressive towards them and she will be a happier dog and not be so aggressive towards you and your son.
Just my thoughts. |
