My Silken Windhound is the same! One moment she's napping on the couch, and the next she's racing through the yard like a rocket. It always catches me off guard.

Totally! It's like they have a turbo mode.

Absolutely, it's a Silken thing!

I know what you mean. My Silken Windhound shifts from calm to zoomies in seconds. It’s one of the best parts about having this breed.

Definitely, mine does it too. It's amazing how fast they can switch gears.
