My German shepherd is 6yrs old and recently lost her companion. In the past 6 weeks we have seen a strange behavior. The first 2 weeks after the death, she would take the box of treats and place it in front of the back door, then take individual treats and place them in the spots the deceased dogs would sleep. Now she is getting into the pantry and taking protein bars, fruit snack and placing them in our beds, chairs and hallway. She is not eating anything just putting them under pillows and blankets through the day while we are gone. My vet wants to medicate her and we do not agree. Today when I got home I found the pizza box in my bed and the left over crust in different bed rooms and placed in chairs, she didn't eat anything just placing the food . Has anyone experienced this. Please help. Thank you
