Nutmeg fell apart when Baz died, but she had only been here a short while. I ended up having to get another grey, for her sake, before I was emotionally ready. Although I intended to get her a young, lively playmate, I came home with Scout, a dignified senior. He gave Nutmeg the stability she needed and she bonded closely to him. It took me much longer, but that was okay. He was a bounce who needed a home.
Scout died last summer and I thought Nutmeg would go nuts again, but she did much better than I expected. I think keeping to a strict routine helped, and going for lots of walks and rides in the car. A dogsitter had been coming in to help with Scout in his last months, and I kept her on to maintain a constant in Nutmeg's world. But I again got another grey much sooner than I thought because I was the one who just couldn't bear the house being so quiet.
Whatever happens, you will come through it. Sending hugs to you and your beloved pups.
