Sorry to hear that Dave. We've been contemplating that same decision lately. Ours is close to 19 years old (Rat Terrier) and has lost most of her hearing and eyesight, lately she's starting to show trouble getting up and down the stairs, even fallen down them a few times. Just when I think we've decided it's time, she must hear us talking as she'll start running and doing figure 8's out in the yard wanting to play.
