Found this juvenile in my basement, the first of many, before they grew too big to get through the cracks in the foundation. **ID confirmed Vermont Reptile and Amphibian Atlas submission, confirmed 7/27/12, reviewed by Jim Andrews - corrected my suggested ID of Green Frog "Your frog is a young American Bullfrog. Bullfrogs and Green Frogs are very similar. I can see from your photos that your frog does not have the ridge on either side of its back
that is a good field mark for Green Frogs."
