Sad Dog

Nevada our Husky is missing Lily our recent deceased rottweiler/shep. At our home he has never been without her since he was 6 months old. He was taken 2x & gone for 6 weeks & 2.5 months. When they were pups, they would snap at each other & I would move my hand quickly up & down between then and say "no bite" . They would snap on both sides of my hand & never touch me.
