Every day, our Lab puppy gets a little wilder. Biting, chewing on things, using the potty inside. I know she is pup and will outgrow this behavior (I hope), but it has been so long since I had a puppy that I don't remember what this was like. She was doing great with the pottying outside. I still take her out every 30 minutes, but now a lot of time, she will not go outside and as soon as we come back in, she will go. Any advice?
