She's 10! And she's still getting along well, albeit her naps are a little longer and more frequent. She's our "hero" dog as she came and alerted me (well, jumped onto my chest when I was asleep...and she never gets on the bed after goodnight cuddles) when my husband collapsed in the hallway one night due to dehydration. I never would've woken up otherwise as I'm a power sleeper.
(What's the phrase about "Mad dogs and Englishmen run in the noonday sun"? One should not go running in the summer in Las Vegas, NV; right, Husby?)
We love our Gabby dog.
