Okay , so for the past 3 night when I go to lay down for bed , my Shepherd within the first 15 minutes of me laying down , she jumps up on me bed , goes to the window , and starts panting and shaking. Its not a normal pant either , its much more accelerated than usual. I cant figure out anything for the life of me. She has been to the vet and is healthy as can be. She doesnt have to go to the bathroom because I let her out and she jus sits there and looks at me. So when I push her off the bed because I cant sleep with the heavy breathing and shaking , she whines and starts to nudge me with her nose. Her nose is very moist and her ears seem warm to the touch , well , warmer than normal. She is not hot as it is about 60 degrees inside the house and mid 40's to mid 30's outside. She never has done anything like this before. I lit a fire in the fireplace for the first time 3 nights ago and I wonder if that is having some sort of effect on her? Weird thing is she sleeps right next to it while it is going and I put it out a good hour or 2 before I go to sleep. I have tried massaging her to calm her down , and I have also taken a night and tried to ignore her and let her deal with her problem and go through the process. Neither one seemed to work. Tonight I will be sleeping in the Living room on the couch next to where the fire is to see if it makes a difference. If anybody has any ideas , PLEASE let me know. I have only gotten about 4 hours of sleep the last 2 nights. She sleeps all afternoon while I go to work. Thank you for any answers tips advice ANYTHING.
