I was going to say try a different girl but if that is not an option... is there anyway she could come over a few times while you are also home? Jackson would not take to a stranger who came into our house w/o me home so if I were to hire a dogwalker, I would first have to be there with them to get them acclimated to each other so he knew she was "okay" in my book as well.
What is Gatsby's favorite treat... ALL time favorite? Jackson's is cheese. I would definitely be using a very high value reward every time the dogwalker is around, that way he begins to associate her with it. The way to a dog's heart is thru their stomach
