At the park today, Sophie was agitated by a person who frankly looked like a homeless person, and she was definitely on guard. Suddenly she seemed huge! She kind of prances when she is agitated (or super happy) and looks a bit like a show horse. I told her I see it no worries, and she still played at being the show pony, but there was no additional growling. The gentleman went past, and all was fine. Even as he went past us, and kept walking she kept watching him. Such a good girl! A little while later the sheriff showed up and took him into custody for vagrancy and something else. I think the park ranger called in on him. She CAN look very menacing.
