Caught a frog in sioux city Iowa 3 days ago while passing through, stopped at a place called bacon creek and caught it. Its obviously a tadpole as the stub for the tail is there as it grows back in. I wonder if its a young bullfrog but it has some spots. Are they from being a tadpole and will go away or what do I have? Snout is not narrow enough for a leapord frog and the spots are too small... Suggestions are greatly appreciated, will have pictures up soon as well as pictures from reptile gardens up in South Dakota.
