When fishing in a river the line should be cast upstream. Casting upstream and retrieving with the current results in the spinner/lure sinking faster.[1]
Walking the dog
The key to "walking the dog" is making sure that there's some "line slack" immediately before each jerk, and immediately after each jerk. This gives a crisp, natural motion to the lure, unfettered by drag of any kind.
The action;
After splashdown, hold the rod low with the rod tip about 1 to 1.5 feet above the water. The lure can be activated strictly with wrist action or by using a whole arm motion that pivots from the shoulder. Switch back-and-forth between the two to prevent overuse injury to any one joint. Due to slack in the line, the rod-tip must move considerably farther than the lure.
With an eye on the lure, keep the pulls short, about 6 inches "at the lure". At the end of each down-stroke the rod-tip is almost touching the water. Then without any pause, the rod is immediately returned to its original position.
The left hand operates on a separate brain, taking up slack line as it becomes available, while always preserving a little slack.
From the angler's standpoint, the delivery is a non-stop series of rhythmic strokes that jerk the lure by snapping slack line.
This causes the lure to zigzag about six inches (15 cm) to alternating sides without pause. The rod-tip must move further than six inches to overcome the line-slack, otherwise a short jerk would be unproductive. From the fish's standpoint, it's a frightened creature that's basically treading water with a lot of wasted motion. The success of walking the dog is partly because the lure never stops moving, making it difficult for bass to get a good look. In addition, the lure spends its time scooting back-and-forth with little meaningful forward progress, in other words, walking the dog offers deceptively slow coverage yet the lure is hard to identify.[3]
