Flirt pole help my puppy like walks?

I live in an apartment complex and my dog hates it outside. He will not go for walks. He’s about 4-5 months and is just scared of everything outside. I hand feed him and train him in front of my door, sit outside with him, but nothing it’s working. I hired a trainer but I don’t think he will progress ☹️. I’m at my wits end. He currently uses the potty on my patio and I’m tired of cleaning it and changing the pads. I tried the grass patch and he just ripped it up. What’s weird is that he will use the potty on grass at my mom’s house! While this complex is dog friendly, it isn’t set up for dogs. I wonder if he feels a bad vibe here? I find it depressing because it’s all concrete. My lease is up in AprI’ll and I can’t not wait to move 🙁

Back to my question lol sorry dealing with the puppy blues here and needed to vent! Will playing with a flirt pole help him get excited about the outside?
