Hitting

If ANYONE has ANY suggestions on how to get my child not to hit, I'll gladly take them. She hits everything and everyone, including herself when she gets angry. I told her to get out of the dogs water...she hit herself. I told her to stop banging on the keyboard, she hit the keyboard. I tell her no for something, she hits me. It's getting old and I don't believe in spanking, especially not for hitting...so yeah. No idea what will work. She doesn't seem to grasp the concept of time out either.
