You can also get a friend to volunteer to help you. I would start with putting Pip away when a guest comes and letting Pixie to the door where Pip can see. Have your friend knock on the door. Ignore the barking and keep knocking on the door until Pip stops. Praise and treat!
Move up to tying him with his leash to something around the door, but away from Pixie. Repeat the knocking. You want to try and desensitize him to the sound. Praise and give treats when he stops barking. Ignore him though when he is. Don't look at him or say anything. Getting rid of the barking hopefully will fix the lunging. Good luck!
If all else fails just know when guests are coming to put Pip in another room. |
