30 days is a long time for a dog to be away from their owner. Something must have happened and those 30 days might take months to undo.
First, cross her off your puppy sitter list. Second, you are really going to have to work with your dog. Patience, firmness and consistency. When around others, I would muzzle it until it has earned your trust. Dog bites must be reported so your dog now has a record. If it happens again, it most likely will be taken away and put down, so it is up to you to work with the dog and investigate why the behavior changed.
He is your friend, partner, defender, your dog. You are his life, love, his leader. He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of such devotion.
The only options you have are putting the crate in another room and shutting the door. It may muffle the sound. One trick I did with one of my dogs was put a sheet over the crate like a bird. it worked well for her.
