If you bought the spro popping frog, then fish it as you would a popper - very effective.
If you bought a normal bronzeye one, then I would suggest you walk the dog over areas with little vegetation, and fish it real slow in heavy vegetation (mats/pads) stopping over holes in the vegetation.
I've caught pike and bass on them.
Just out of personal preference, I tend to break into the plastic a bit by collapsing the frog a couple of times, since spro plastic tends to be stiffer than most.-When it comes to frogs I will take what ever hook up advantage I can get.
Also, spro frogs will fill up with water-Some people completely close up the holes to prevent this but that might hinder hook ups since the frog isn't collapsing as well.
Good luck, hope you get some awesome topwater fury
