My family left to go to Mexico for three days due to my grandfather's death. I was willing to lose my job to attend my grandpa's funeral but my mother told me that it really wasn't worth it. Grandpa was gone and losing my job wouldn't bring him back. With guilt and regret I stayed home.
First night alone, everything went smoothly. I would hear an average crack sound which could have been anything. (The heater, maybe even my dog.) Second night, I remember I was watching Jeepers creepers in the family room. It was getting dark. All of a sudden I heard footsteps coming from my parent's bedroom upstairs. I choose to ignore it. You know nobody wants to believe they just heard footsteps when they are all alone. Later on that night, while still watching TV I felt like if there was something behind me. Again I ignored it. But then, I choose to listen really closely to what was going on behind me and I heard someone take a very deep breath. At this point my heart was pumping really fast. All I could think at the moment was,"i need to lock myself in my room, get some rest." I ran to the TV, turned it off, then went upstairs, locked my dog in a cage in my sister's room, then closed my sister's door.
I was finally in my room, laying down in peace. I was to the point that I was falling asleep but still wake. Then I started hearing my dog bark. Loud, and very violently. I sat up on my bed and just listened for anything unusual. When all of a sudden my dog started scratching on my door. She seemed very frightened. I opened the door and grabbed her. She was shaking vary badly. Like if she just dodged a car or something.
I checked the entire house after that. I was in tough mode walking around with a bat. Everything in my house was in place, all doors and windows were locked. The only thing that gets to me is, how did my dog manage to get out of her cage? Not only that but how was she able to reach the door handle and open it? By the way this is a Toy Puddle we're talking about.
In all something strange happen that night. And I'm for sure that there will be many other nights just like this one at my house.
Anyway, my little boy put Foxy in her cage one night, and an hour or so later she was at the side of my bed. I just assumed Dalton didn't get the cage latched right. Next night, though, I locked her in and she was in my room less than an hour later. The following night, after putting her in her cage, I sat in the recliner beside her, just watching to see if the latch had a malfunction or if she was smart enough (or hyper enough) to be able to open the latch. She did push on the cage door with her front paws, but nothing happened. I sat there for at least half an hour just watching her. She eventually laid down. She was let out of her cage so many times I quit putting her in it at night. (It also made things a lot quieter at bedtime 😆) I ended up giving the cage to a close friend and he never had any problems with it opening on it's own. Go figure.
We did have a little girl spirit who lived with us and she was pretty active. So I think Emily was letting Foxy out. Since she was only 3 or 4, she probably felt sorry for the little doggie!
So, after my long comment, I think that could be a possibility in your case, too. In my case, though, our dog wasn't scared as your's was. She was ridiculously happy!
