1 I wouldn't take him for a walk
2 I'd keep him in cage in front room or where ever you spend most of your day
3 I'd book first week off to be with dog just incase he hurt himself or get someone to watch him
4 I wouldn't even leave his side at night. You may think I'm going over the top but have I brought my dog home she almost died in middle of night due to poor stitching from vet.
5 I'd sit next to the cage to reassure the dog it's gonna be ok
Second week all depends how energetic your dog usaly is mine is about as energetic as a dead rechargeable battery that struggles to hold any charge all she does is sleep eat and walk and a bit of play but not much since she's a lazy cow.
If he's like my dog and sleeps anyway take him out but keep him in one room. If he runs around hyper it's best to keep to vets advice.
It will be hard on you both
Good luck
