My name is Jane and I've been working professionally with dogs for over 18 years now. It will be my pleasure to work with you today. I do have some questions and a question answer format works best for this type of situation since it will likely take me 30-60 minutes to type up a response once I have you answers.
What obedience training has she had?
Is she allowed on furniture?
Is it always at the door?
If she has had obedience training does she listen even if people are there?
What have you tried so far besides socialization?
Are you worried when you walk her on leash and people approach?
You have been using treats to socialize her. Has it made much of a difference in her reaction on walks?
I'm going to switch over to question answer format and wait for your replies. PLEASE DO NOT RATE THIS CHAT PORTION until I have supplied an answer to your question. I will do that after receiving your replies.
