Hi, I have a she-mutt named Lucy. We got her from the Humane society over the weekend. She is 7months old. She has a few issues but is over all a super sweet girl. I am having issues with her going potyy outside. She seems to have changed in the past day. She used to do her business in one area, but now If I take her out and use a prompting word she sniffs around and then lies down. When I try to get her to get up she just lays there and I have to practically drag her to the house. I don't know what the deal is. She hasn't pooped since last night at 5pm...Any ideas?
