So good to hear, Cedar. I think he'll be great for your son and your household. Just a thought: we use this routine with our dogs (minus the walking) when feeding, maybe this is a responsibility you can give to your son? It's easy to teach and once our dogs knew that they need to sit and be calm before they can eat, anyone could do that routine.
It's something we'll be working on definitely; both of the boys have been very good at helping out with Moshi so far -- we just all sat down outside the shower and each did our part to keep him happy, clean, and in the end: FLUFFY! One thing we've identified that needs work is getting the boys to, I guess, respect Moshi as an individual, if that makes sense? They adore him but are a bit too rough and don't really know their own limits, let alone a tiny puppy's.
I don't know how old your sons are, but it makes sense that they see Moshi as just the new toy for now. A new (super fluffy!) toy that can't clearly communicate where the boundaries are and that didn't come with a manual. As Moshi grows he will be better able to bark back, but until then, it's up to you and your wife to teach where that boundary is.
