Vintage Glass Scotty Dog Christmas Decor

I was told this could be Depression Glass. “30” is stamped into the glass on the bottom. Could it mean 1930? This would make an adorable business card holder, flower vase for short buds, desk organization for paper clips, rubber bands, pins, etc. Measures approximately 3” x 6” at the furthest tips. In one photo you’ll see a small divot groove circled. It’s not a chip, just part of the glass production techniques of that time. Great condition!
