Here is some excellent reading for you. It's free. But if you're in danger, I seriously think you should get a certified behaviorist to help you. Of course, you must be careful who you get. I know you said already that you can't afford that. So pleeeeeze don't swear at me.
You have the right to remain silent. If you can not afford a behaviorist, one
might be appointed to you by the court. I don't know about the rest of you, but when I think of all the frivolous lawsuits that occur and they win, I can't help but wonder when or why someone doesn't try suing the National Geographic people who produce this dangerous dog whisperer show.

Of course, that does not include the bit about your dog going after the cat. That is just something dogs sometimes do, as it was explained.
He never did it before....Behavior never stays in one place. It changes
constantly. There are a kazillion variables that affect behavior every second of the day. With the cat, keep them separated. What the dog did to your wife sounds like he didn't mean to bite your wife, but redirected his predatory behavior toward her out of frustration...not a consciously thought out thing. With the other stuff, I wish you the best. Please read these articles, at least for a start.
