[dogbert]

We actually went through this a year ago when I had to put our 10 yr old Lhasa Poo to sleep. Only it was the cat who was lost without her not another dog. Sassy had never lived with us without Millie and she just kept waiting for her to come home. She would come to the door every time we walked in and look at our feet. One time she even leaned around to look behind us to see if Millie was there. She'd meow and walk the hallway, look on our bed etc. I took all of Millie's stuff away thinking I'd never get another dog. I kept her favorite toy in my dresser drawer. Sassy would sniff where her kennel was and food dishes. She found the kennel in the basement and would sleep on top of it sometimes. In time she came around to her old self again, but like us she needed her time to grieve.
