My personal rule of thumb is first week NO exercise at all, crated or leashed at all times and under constant surveillance. The second week I allow a tiny bit of freedom, if they can roam without running or jumping then I will remove the leash but they are still watched at all times, I also take them for easy walks on leash. Third week if the incision site has no swelling and is looking healed (as it should by this point) then I allow free rein to play and romp but still check it a few times a day to ensure they're not overdoing it. By 4 weeks it should be 95% healed and back to normal
In the meantime you can use frozen raw bones (freezing makes it last longer) I use knuckle or marrow. Stuffed kongs that are frozen (kibble and wet food are my go to though I switch it up with peanut butter, yogurt, etc). Also use mind games (puzzles, easy obedience). A fun game is the cup game (like the pea game for humans but changed up for dogs) using a few plastic cups and some treats.
