are basset puppies supposed to be so needy?

my 5 month old basset seems to have a hard time being alone. when I take out the trash or run out to my car for something, you would think the world is ending the way she cries. it doesn’t seem like she can’t play independently – she just doesn’t want to be alone. I’m really beginning to wonder if she has separation anxiety going on. When I’m busying myself around the house, she’s locked in my living room with everything she needs (so she doesn’t get into things or chase my cat) , she can see me as I’m walking back and forth. But she can’t relax. Once i sit down on the couch, she will play with toys or take a snooze. Maybe just part of the basset stubborn nature i don’t know.
