How much of a role has/does your husband have in his training? Does he respond to commands from your husband and is just a terror when it comes to eliminating and such, or does he ignore commands as well? Also, how old is your puppy?
My first thought is that your husband needs to work on establishing a relationship with the puppy, without you around. He can start by doing consistent obedience training with the pup, taking him for walks, and maybe even keep Huter tethered to him in the house for the time being (both to help them bond, and to help him head off "accidents" better). However, if he's already regularly training and walking the puppy without you there, then it may be a more complex situation.
Also, look into NILIF (nothing in life is free). That can really help with situations like this, as long as you both practice it consistently.
