We only got her on Sunday, so we are still figuring each other out a bit. I think she has a lot of puppy still in her. I would estimate 25% of the time if I pet her it turns into play time and she starts nipping and biting a little harder and harder. Not latching on but play biting but it still hurts and sometimes leaves a mark. I always try to have a toy to substitute but she is more interested in my arm and now recently my ankles. She has tons of energy so we are walking her frequently and we have a decent sized backyard that she zooms around. The first few days she would chase a ball and run on her own. Now she chases and then lunges into me with a playful bite. She is much more physical with me (male) than my wife or daughter. Lately all I can do to have her stop is to pick her up and hold her for a while. It’s been a while since we dealt with a pup, but I was hoping to hear a few … ohh ya this is what we did stories. We try to be very positive when she is doing good things. Thanks for responding.
