He is, indeed. I can't believe he's still alive. He's 15 and that is well past the expiration date for a big dog. We are not keeping him going for our own wants, which some do. He still likes going out and doing dog stuff like sniffing to see what animals have been in the yard and looking at the deer. But he has a hard time with steps (cognitively as much as physically), and thinks he can't jump on the couch or chair anymore. He has congestive heart issues, among other things, and I'm always balancing his meds to keep his breathing as easy as possible, but not strain the kidneys too much or dry him out. He's a lot of work and we haven't had a full nights sleep in months, but he's worth it. When we wake up, we're just glad he's still alive and are thankful for each day.
