This strange behavior started on Monday night. She refused to go outside to pee before bed, running to her kennel and panting and shaking. I thought maybe something outside scared her-a loud noise or something. She didn't want to go out the next day either, and usually she will spend all day outside if I'm off work. She seems to be eating,drinking, pooping and peeing normally. when I take her for a walk no problems. thing is she's taken to hiding in her kennel and shaking and panting like crazy. I see nothing physically wrong with her, but wonder if I should take her to be checked out to make sure. Any ideas or suggestions? this one has me stumped. I can't see anything wrong with her and I have no idea what to do.
