No, it's not recommended to get rid of him as your 1st option. As someone else stated, seek an animal behaviorist/dog trainer. Without any other information-It's possible that he thought you were "attacking" your husband, especially if he see's your husband as the Alpha of the pack, or he could of thought that your husband was "attacking" you & was just following his leader. I'm curious as to what you or your husband did after the bite? The dog will sense if you're now fearful of him & it may or may not change your (lowering) status on the K-9 totem poll, therefore he may display more dominance towards you. (Dominance doesn't necessarily mean aggression.)
Either way, if you've never had behavior problems before this, after this & he's been apart of your family for 3 years, getting rid of him should be a Last resort. If that does become a real option for whatever reason, he most likely won't get a home, he'll be euthanized. You can't pass on a pet to another family with unresolved behavior problems, just to pass on the behavior for someone else to deal with & that's if your honest with the dogs problems & could actually find someone to take him. Shelters will just "put him down".
Most people humanize dogs (We can't help it!) & are unaware that no matter how domesticated dogs are, they are still pack animals & live there lives according to the laws of the pack.
Try to educate yourself on K-9/Wolf pack behavior by talking to a trainer or research info on the internet & that will give you some insite into the behavior of dogs. Good luck!
