I don't know what to do. My other dog just started acting incredibly weird seemingly out of no where. Last night I had to kick her out of my bed because she just wouldn't go to sleep, like she was scared or worried about something.

She's still eating, but now I can't get her to play at all. She's been acting like she's afraid of something for the last 2-3 days. Her ears are constantly back and her tail is always down. She's never acted like this before. She was fine the first few days the puppy was home, and seemingly took a complete 180 overnight. I'm really worried and frustrated, and I don't know how to handle this. She's been getting tons of attention, I haven't been ignoring her at all. Nothing seems to be breaking her out of this.

She even pooped in the house today. She'll go outside (we have a doggy door), but she won't leave the porch.
