Here's what Rover, the Dog 'n Suds mascot, presently looks like on the bottled root beer sold in grocery stores and online. At least the design is an attempt to mimic the pose still seen on the classic sign.
I used to be able to find the bottled root beer on the shelves at the Bi-Rite Express in Sheffield Lake. But it disappeared from the shelves a few years ago and I've never seen it anywhere else. So instead I buy it fresh by the half-gallon at Ilene Hampton's Dog 'n Suds on North Ridge Road. There's no label on the plastic jug, but maybe it's just as well.
