I have been frogging a few other times before, and I am planning another trip tonight. Just wondering if someone could tell me a distinct way to tell the difference between a pig frog and bull frog. Last time we went we seen a bunch of smaller frogs that we thought were small bull frogs, but the more I think about it, they might have been pig frogs. I want to make sure I don't pass up anymore frogs that are legal pig frog size thinking that they are under sized bull frogs.
