These are the NEW Pro Dawgs from Musky Innovations with a flexible jointed internal harness. This harness has a different weighting in it verses the traditional Pounder that gives the bait more head down action and more hop. The added flex and different weighting to the Pro Dawg gives the bait a different action than the original Bull Dawg. Just another tool for the box when on the water musky fishing. Try a few you won't be disappointed. This is the 16" and 15 oz Super Mag or Pounder Size. Many of these colors are exclusive to Team Rhino Outdoors.
