When we "inherited" Darcy from a relative who moved and couldn't take her, we thought another dog was the last thing we needed. We already had an aging, ill dog and a younger one that was quite lively. There was a period of adjustment, but they soon sorted out their pack order and all was well. We lost the older one as anticipated but then also lost our younger girl to a sudden congestive heart failure. I can't tell you how good it was to come home from that tearful trip to the vet to the loving attention of Darcy, the dog we didn't know we needed.
