We brought Cali home a week ago and she is always attacking/biting my kids, especially my 4 year old. My daughter cannot even be in the same room as Cali when she is playing or Cali will focus on "getting" her. My daughter has numerous bite marks. I feel so bad because I do not know what to do. I have to include my daughter when we are playing with the puppy but I am scared for her getting hurt too badly. Just today when we were leaving to pick up my other kids from school I sent Emily out first with Cali and not 5 seconds later my daughter was screaming because Cali had her by the dress and had bit her leg. She just will not let go. Any advice? I keep Cali gated in the kitchen (her crate is in there too) as much as I can but I do not want to keep her in there all the time. I have read about when the puppy nips to make a loud yelp and turn your body away. But this is not working. Cali is relentless. I have had to start putting her in her crate when she acts this way, even though you aren't supposed to use the crate as punishment. Please help!
