Yeah, that is sad. She seems healthy though? No aches or pains? I think what finally got us with Jo was when she couldn't get up the stairs anymore. She still had an appetite and as much energy as you could expect from a 14 year old dog, so that made it hard. After the fact someone made the comment "she's ready when you are ready". We probably made Jovi suffer longer than we should have, but she had no way of letting us know. It doesn't sound like you are at that point yet though.
