Looking for some advice! These are our 2 girls, German Shepard is 5 and lab mix is 1 and a half. The lab mix was adopted from Forever Home July 2014 and we just love her! They have been best friends ever since they met and have always got along so well. Over the past month they have been fighting and it has been increasing and getting worse. It has really come out of nowhere, we never ever expected this, there were never any signs of anything but love between them! Anyone have any suggestions of trainers or anything else we can try? We've met with one behaviorist but are definitely open to any and all advice as they are our family and want to do whatever we can to keep the family together!
