//Soooo for some reason my dog, Nala, keeps acting weird. She seems to be afraid about something about the garage, and my main worry is that maybe someone else is living in this house without us knowing??? That may not be it, but why else would my dog be freaked out for seemingly no reason? She's been seen laying in the kitchen, dining room, pantry/laundry room, in front of the fridge, and in my sister and I's bathroom. The weirdest part is hat she was trembling when she was in our bathroom. It's so weird... My mom and sister don't have any ideas about what could be bothering her other than that there's something wrong with her.

//Do any of you have any ideas about what could be the problem?
