Like the others, I'm so sorry to hear about Shadow. Grieving is such a personal thing - some do well with remembering, others immerse themselves in other things for awhile until the initial pain dulls a bit - it's all okay. I agree with the poster who mentioned that your dog was playing almost to the end & had a great life with you. When you're ready, cherishing the memories can be a comfort, but everything probably seems too painful right now & my heart really goes out to you.
