I have two rescues, who can tell me what they are?

First three pictures are of Dexter how he usually looks, and the next two he has a haircut. He's definitely daschund and something, I'm just not sure what the other half is. He's got all the textbook doxxie personality traits and crazy separation anxiety. He's also weirdly barky sometimes at totally random things. My other dog can be kind of reactive so I think he's picking it up from her a little bit. He doesn't like being picked up and is VERY SMART. Sometimes you can see the little gears in his head turning, and if you do a gesture enough he figures it out quick. He's a bit territorial about treats and toys, but also loves to play with the ball. He is roughly 15lbs

The other dog is Harley. I found her in the woods in Mississippi a few years ago and we've been besties ever since. She's got a pretty small head compared to the width of her body, and she loves to use her paws for stuff. she even points on her own sometimes. She's got the thickest, sheddiest coat on this entire planet somehow. She's extremely prey driven, she even systematically killed an entire litter of possums over several days on her potty breaks once. It was terrible. But she'll chase anything that moves, and lose all interest once it stops moving even for a few seconds. She's scatterbrained and doesn't really focus very well, but she's the loyalest, most loving, affectionate creature I've ever met. She also likes to start shit with strange dogs for some reason. She can see s dog her size across the street and just stare at them, but if it's a big dog she's just gotta start barking. And if anyone comes nearby she barks too. She also freezes completely in public new places so I cant take her to the store without it being a whole production. She's very unique and idk where to even start. She is roughly 30lbs

I'm sorry if this is way too long!!
