Hello and Welcome to YT! Miss Paris Pancake sounds like she is doing very well for her age. The biting and walking, will get better with time, patience, consistent training and age. Replace the hands and fingers with toys. That is a great distraction. When Twinkie was young, she would watch my feet as I walked and nibble on my ankles. She is 8 months now, so that is no longer a problem. The puppy stage is trying, yet so wonderful all at the same time. Good luck and enjoy the new addition to your family!
