Hello I have just joined this forum and was wondering if anyone could help me. We have bought a German Shepherd Pup and will be picking her up at the end of Jan. She is one of 7 pups. They are with both parents in a good family home and look ideal. I already have a cross Jack russell who is 5 and a very gentle lovely little dog but I have been told that GSD can be very dominent and to be careful because she could attack my Jack russell. I am getting all worried now. Of course I am hoping that we can give both of them lots of love but I dont want the new pup to get jealous and attack our other dog.
