OP I would do a trial and sleep down with your dogs for a few nights and see if something changes. Sorry to say, but the wife not wanting the "dog smell" pretty much went out the window when she agreed to have 4 dogs. I'd definitely avoid the bark collar on a 4 month old puppy. Not of fan of them to begin with but that's just my opinion and me never having a super barky dog.
Does she get annoyed with the barking?
