I had a different answer until I re read your post. Your only option is to move your horse. She probably sees you as a pest having to drop everything to get the dog.
If she is depending on this board money, move out and tell her you'd be happy to return if she can prove that the dog will not be outside when you arrive to ride. Offer to call and give 10 minute's notice.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
