Go for more walks together, teach him tricks and do training together, feed him at least once a day if your hubbie wants to feed him the second meal then it is a good balance. Soon your dog will begin to look to you more for guidance. Most dogs will prefer their main caregiver over the secondary, unless the secondary person purely spoils them. Spoilers are seen more as a source as empowerment not guidance which can create naughty little dogs, so don't let your dog get too spoiled.
