Ohio's Frog and Toad Species

It's ranid and it's colouration rules out all but Bullfrog and Northern Green Frog for your area. It has dorsolateral folds on it's back (raised ridge of skin running down each side, they're pretty clear in the 3rd pic from 1st post), this rules out Bullfrog making a Northern Green Frog the only possibility.

Glad it's eating and good luck!
