Hi, I have a 1 1/2 year old female German Shepherd who sleeps in bed with me every night. The other day, out of nowhere, when I shut my bedroom door, she had a sudden anxiety attack, scratching at my window and door trying to get out. Once I let her out of my room, she sleeps in the hallway or on the couch just fine. Does anyone have an idea of what may be going on? I tried giving her some dog-friendly sleep medication but it did not seem to help much. Thanks for the help!
