Re: She thinks I'm kidding
Dogs live in the moment, so when you spanked her with a newspaper for being inside, you punished her for finally being inside- which is what you wanted. If you punish her for coming inside, why would she want to next time? Also, hitting a dog is never the right thing to do! She is still a puppy and might not be able to handle that much off leash freedom just yet. Keep practicing the come command with lots of positive rewards, but in a less distracting/fun situation, then work up to an off leash park and try it again.
