It sounds like she IS having some hearing loss. Dogs with partial hearing loss often can hear some things but not others, some tones & not others. You can stand outside with the dog standing rite next to you & say something to the dog but the dog can't hear you but other times it can. Sometimes it's as simple as wether your standing up or down wind of the dog when your talking. So I don't believe it's got anything to do with her brain but rather some slight hearing loss. Also it sounds like she may be having cataracts ? if so then she can only see some light & shadows so tell your husband that NO she is NOT doing this on purpose. Remind him that someday he will be in her shoes/paws.
