I swear he’s not a snake

He’s a dog. He is active ALL DAY and ONLY calms down AFTER I take him out and play with him for a bit. I thought maybe he was hungry today because it’s been almost a week but nope, he wasn’t hungry. He waits at the tanks doors for me to open them. Then he just slithers out onto my arm, waiting for his next adventure. Anyone else have a snake who doesn’t act like a snake?
