Pomsky advice

I need advice on how to handle my pomsky. he’s 2 1/2 and I’ve had him for 2 years. I’ve been hoping he would calm down a little with age but he’s still so rambunctious. He’s the sweetest thing but he’s so wild. I have to keep him in his crate when I’m not with him which I don’t like doing but if I leave him out of it he will destroy everything.

he never gets tired, I have a large yard that he runs in, but it is always a battle to get him back inside. and he doesn’t even like treats that much. sometimes I can get him back inside with one but usually he will show he wants the treat but realizes he’s gonna have to go inside to get it and doesn’t care about it anymore.

I knew I was signing up for an energetic dog, but he’s dominantly husky and he’s a lottt bigger than what I was expecting when I got him. not that I wouldnt have taken him, but the person I got him from said he wasn’t supposed to grow any more and that just wasn’t true at all.

I’ve recently gotten him on medication prescribed by the vet and the first day it worked TOO well, he barely wanted to get up. but since that first day it has not worked AT ALL.

literally any advice is welcome
