I feel sorry for you. I have seven dogs and really don't want to think about when their times will come.
Here's a great quote:
Near this spot are deposited the remains of one who possessed Beauty without Vanity, Strength without Insolence, Courage without Ferocity, and all the Virtues of Man, without his Vices. This Praise, which would be unmeaning Flattery if inscribed over human ashes, is but a just tribute to the Memory of Boatswain, a Dog. ~George Gordon, Lord Byron, "Inscription on the Monument of a Newfoundland Dog"
