Spanky looks a lot like your Picky in the face and in coloring. We also run into a lady walking a dog that looks like him. It always makes us laugh because, at a distance, it looks like we're approaching our own dog being walked by someone else. The lady says hers is a JRT/poodle mix.
Interesting that Spanky looks like 2 poodle mixes, but he doesn't seem to resemble the poodle part. He probably more resembles the schnauzer and the JRT. The pound did call him a terrier mix!
