"Attitude" problems are usually a problem with them not respecting you as alpha. The dog has learned to be dominant, and that is a tricky habit to break. Huskies are especially hard to train, and have an abundance of energy. It takes alot of work and patience, and I'm sad that you are looking at having to re-home him. Was this pregnancy unexpected, or did you TTC knowing this was going to be a problem?
You said you tried behavior modification, but have you tried taking him on a morning and an evening walk to tire him out? Some dogs are much more obedient when they have been mentally stimulated.
Also, the snuggles and playtime could be contributing to the problem. Some experts believe that letting the dog on the furniture is recognizing them as your equal. I tried it with my dog, and it's true for him, the more he's allowed on the furniture the worse he behaves. It seems cruel, but it's better than sending him away if it works!
Playtime should be an outdoor activity only, so he learns to be calm inside. If he barks, acts aggressive, or extremely hyper, do you have a yard that you can put him outside in? Don't ever communicate with your dog when they are acting out. Remain calm or it will only escalate them. Ignoring them goes a long way to establishing dominance.
Have you tried the tethering training to establish dominance? It can be inconvenient but it works. You tie a short leash to yourself and the dog, and they have to go where you go all day. They learn to watch your body language and to follow behind you. Body language is everything to a dog, and even the act of letting them barge through a door in front of you means something!
If you really have no choice but to re-home him...
I hope you will release him to a German Shepherd or Husky rescue (there are a few on the East Coast) that can find him a suitable home. With a strong will like that, I am assuming that someone with knowledge of Huskies would be able to do some training and possibly rehabilitate him. At the very least, they may be able to find him the perfect home and he won't be at risk of euthanasia in the meantime.
