His Royal Herbiness has just celebrated his eleventh birthday. Unlike hobbits, he won't live to see his eleventy-first birthday, but I'm pretty happy with eleven. The Cortaflex HA (with hyaluronic acid) seems to have given him a bit more flexibility, and he's no longer pushing his hips into my hands, saying "Rub my rear", so I'm assuming it's doing something.
Happy Birthday, old white-faced dog.
