I lost my beloved 13 year old Aussie 2 1/2 years ago. Even though I have new Aussies (which are wonderful) I still sometimes burst into tears when I think of her. How sad for this young lady. Simply heartbreaking.
I think the suggestions to print a picture on fabric and put it as a label is a wonderful idea. It would be like the pup was with them curled up on the couch.
