Drifter

Casey turned 13 today. He's drifting into his twilight teenage years with his customary aplomb.
I doubt there'll be any texting or loud music but sleeping late will be on the cards as usual.

He's been an exemplary dog over the years.
Blipped innumerable times (This was the first).

Fashionable, playful, stoical, whatever the weather.

Good with cats and other dogs.

Familiar with flowers, fungi, and products of the sea.

A long distance walker and a contemplative watcher.

Usually dignified, occasionally daft.

It's been a dog's life!
