Thank you, Kelda, Chrissi, Gil, and Elle for your messages of support. They meant a lot.
Madison was a beautiful dog, very elegant. She really didn't look her age. In fact, just a few months ago, people were still mistaking her for a greyhound puppy and they were surprised when I told them her real age. I hope my girl really had a "sweet life" with our family. I've been slowly putting away her "stuff": coats, beds, toys, blankets, collars, leashes, and just recently, a new soft harness we bought for her after her chiropractor said she shouldn't wear a collar anymore due to neck pain. (Yes, she was spoiled!) I brought her leftover medicines to the vet's office on Friday afternoon. In these trying economic times, maybe some pet owner will appreciate a "freebie."
Elle summed it up exactly with: "One of the things I've heard said is that one of the hardest parts about losing our beloved animals is that they help get us through the tough stuff, and when the tough stuff is losing them, then we don't quite know where to turn." Well, I'm glad I turned to this thread. Thanks, everyone.
