Each day when I leave for work or to go anywhere Coco gets this sad look in her eyes and won't go in her space. She only goes if I carry her and she then hugs around my neck and tries to climb back up my body!! She is 50 pounds and this is getting crazy!! She was better for a while and now it is worse again. She has fun playing with her kongs in there and I can hear her playing as soon as she goes in. I play music for her too. She also gets like this when we go to PetSmart even though I have never left her there!! What to do?
