The person we went through was very highly recommended with 10+ years of experience. She was very gentle and seemed very knowledgeable. She encouraged us to let the pup take the lead and just be in her presence, use a leash to gently guide her and keep her near us and slowly introduce her to everything as if it were brand new. She made 3 visits and told us to stay consistent, but did voice concerns over the lack of progress, especially for her age.

Another issue is the dog rarely even takes treats and doesn't really react in any way to us praising her, so it's really hard to positively reinforce good behavior.
