Frog may not be on the menu. I know that's hard to hear, but bass can be picky like that.
To increase your chances though, I will give you a tip that helps me a lot. Minimize casting all over the place and be selective where you cast. Frog fishing in the summer can be slow if you don't throw the bait in the right location. Frog to me screams vegetation. Not just any vegetation, but the green healthy variety. For example pads and grass. I like to cast behind the grass and pads and land literally on the bank. If the bass are there ambushing bait, hold on to your rod. Bass are ambush predators, so throw in spots that most people wouldn't dream about casting in. Frogs are very versatile and they can handle being fished in those ugly places. Make sure you are fishing with a strong rod and and using at least 50lb braid in dense cover, and 40lb in moderate to light cover. Best of luck to you.
