My 15 month old spayed GSD has started to act odd this weekend. She wants to be outside and won't come in when I call her. I have to go out to get her and she shrinks away from me like I'm going to do something to her. She's been hiding in her crate a lot. I've caught her peeking around the corner at me and when I see her she takes off. Unfortunately this morning I noticed a hot spot and had to trim her hair and treat it - which adds to her staying away from me as she doesn't like to be messed with too much. She's normally loving and wants to be with me all the time. I want to cry as she is so out of sorts. Any thoughts?
