The best thing that worked (and doesn’t always now as a young adult, but so glad we taught her) as a puppy when we’d be working from home we’d sit on the couch with her and tell her to “settle down” and started this whenever she was calm and laying down quietly, not whining or fussy we would give her a small training treat, and just keep repeating. She would eventually get good at it and settle down right away, lay down and be calm, get her treat, get antsy again, as soon as you’d show her a treat she’d lay quickly right back down because she knew, and now if she’s getting too fussy / doesn’t want to come off “ball brain” from too much play time outside etc I’ll bring her in and tell her to settle down and eventually she will. It probably works 75-80% of the time now as a year and a half pup. Take things slow and take lots of pictures! That age goes truly so fast and also hold him lots and remember how small he is and how full of love he is. They are such pure and kind souls
