Of course you can dog-walk the SLIDE SINKER as fast as DOG-X Jr., but when you stop retrieving it, that is when the two baits will come apart completely. While the Jr. will stay put on the water surface, SLIDE SINKER will start to slide-fall slowly like an injured minnow. If fish hasn't struck the SLIDE SINKER yet, then start dog-walk retrieve while the bait is under the water.
SLIDE SINKER will dart from left to right as if it tries to dog-walk in the water. And if you retrieve it hard it will rip the water surface just like a baitfish trying to escape from predator. In this sense Slide Sinker is subsurface rather than top-water dog-walking pencil bait.
