Hello, I have a two year old female german shepherd, and on Sunday we just invited another 8 week old german shepherd female pup in our home. The introduction was slow, and went very well. My two year old is a lover, but she is independent, and enjoys going in and out of our home via the doggie door, to our fenced in yard. The two dogs even are playing pretty well together. However, my concern is that now my older dog does not even want to come into the house. Before, all i had to say was Mia, lets get a snack and she was through the door, but now she wont even come in. She's all excited and wants me to give her attention when I'm outside, but it seems like she is separating herself since the puppy is inside. My heart is broken over this. Do you have any suggestions?
