"You'll know when it's time," our vet told told us. One of our dogs, Rags, is dying and the last couple of months we've done everything we can do to keep him comfortable and monitor his condition to ensure that he's not in pain. "How will we know when it's time to put him down?", we wondered. She was right . . . it was clear to me less than an hour ago that it was time. I'll spare you the gory details but his systems seem to be failing all at once. I had an idea this morning that it was looking grim but a little after noon, it was clear that the time is now. I called the vet and she can see us in a couple of hours.
