I have an 8 year old female Doberman who up until a week ago would only ever make a mess in the house if it was dire circumstances. This past week she has done nothing but go to the bathroom, only poop, in the house and she has no regret about it. Doesn't get nervous when I get home, nothing. Just stands there. She's barely eating, finally after 4 days without eating she ate last night. I'm at my wits end with her. She's single handed my ruining my floors and doesn't seem like she has any intention of stopping. Anyone have this same problem? Should j be concerned?
