My dog won’t always relax when I’m gone.

I know this might be a simple fix, but please read all of this before judging.

Recently, I installed a camera to watch my dog while I'm gone. My dog is crate trained, but my current apartment does not have much room for her crate as she is a bigger dog and her behavior is the same whether in her crate or out of it. I've tried putting her crate back and it did not fix her behavior and I was worried she would injure herself if I kept it.

When she is alone, her behavior is one of 2 polar opposites. Sleeping the entire time, or pacing and occasionally chewing on my stuff. She has plenty of her own toys, but she will not touch them, food, or treats if I am not home. However, my stuff is fair game. I've watched her and it doesn't seem like shes trying to destroy my things, just that's what she would rather play with in the moment. She will occasionally bring me my things to play with when I'm at home but I'll take them from her so she knows they aren't toys. (Shes a retriever)

I always take her on walks before leaving and we sometimes go to the dog park to run around on nicer days. I can not find any pattern in which behavior she will exhibit while I'm gone.

Any help would be greatly appreciated.
