I had something happen today that has never happened before. My female Copper is 15, all most 16 weeks old. I have a friend Beth that has been to my house previously and has met and played with Copper. Today Beth came over and Copper was scared to death of her. Copper immediately went and hid under my bed and would not come out for about an hour. She eventually came out, and slowly walked towards Beth, smelled her and gave her a couple kisses on the hand. This in the past has not been normal behavior. Is it just the age? Is there anything that can be done to work through it? It's not like we never have people at our house. Copper spends a lot of time outside with us and has had no problems with the neighbors or neighborhood kids.
