I'm so sorry to hear about your tragic loss, and about the loss of others who also left their supporting messages to you. I have never lost a puppy before and now that I have had Nina for 3 months, I feel so attached to her that I can't even think about what life would be without her. I feel so responsible for her welfare and I can only imagine how you feel. Sometimes I step on her little paw and it breaks my heart. Now, I just walk very slowly around her. I pray to God that your daughter will truly forgive herself. It really was an accident. I'm sure that your support and time will heal her heart.
