Crate training

Hi Everyone, I’m hoping for some advice. I live in an apartment and put my dog in a crate while I’m at work (he goes in around 7:00 AM, and I’m home between 11–12). My dog has separation anxiety, and while we put him on two anxiety medications, he still barks nonstop when I’m gone. Recently, I saw a post in our community app about a dog in the building barking all day starting around 8:30 AM, and I think it might be ours. I thought the meds were helping, but clearly, he’s still stressed. I really don’t want to cause issues with neighbors or risk eviction. I’m wondering if he might have confinement anxiety in addition to separation anxiety. I’ve tried giving him Kongs or bones and leaving the TV on, but nothing seems to stop the barking or distress. I’m considering whether letting him free roam in the apartment might help.

Has anyone dealt with this? Any advice on managing this behavior I’m at a loss at this point and this is making me stressed, keeping him calm, and making sure he’s not stressed while I’m at work would be so appreciated.
