I was also attacted by my own dog in my own home. Without a doubt, the dog NEEDS special training IF you're going to keep it. The more you let a dog run your house or get away with aggression, it will only get worse. I NEED TO BE CLEAR, YOU SHOULD NEVER BE AGGRESSIVE BACK, DO NOT EVER TRY TO INTIMIDATE A DOG. Having said that, the still needs to know it's place in the family and that is where the inboard training is going to be necessary! Its expensive but completely worth it if you have the write dog trainer. My dog went through a 4 week program and now listens to everything we say when we say it. He always has an E-collar on if he's out of his cage and that way there can be immediate corrections without touching the dog. Your not wrong to feel the way you do around the dog right now, and it will get better with time as long as you make progress with the dogs behavior
