Oops. An unattended puppy is probably never a good idea.
I was otherwise occupied in my studio, and all the sudden, I heard Ricky chewing on something, which I figured was a hoof. So I ignored it for a few minutes but then realize, "Hey! I didn't get any hooves out for the Ricardo's today!"
And then I looked over at Ricky. A blue marker had been chewed into pieces.
