Can't see those pics well; but if an American Toad, it will have one or two warts in each of the large dark blotches on their back and larger warts on the legs tibia. The white chest usually has dark speckles and the parotoid gland (on toad's back behind eyes) is typically separated from the cranial ridge.
If on the contrary it's the similar looking Fowler's Toad, it will have 3 or more warts within each dark spot on its back. There are no greatly enlarged warts on the leg's tibia and the parotoid gland touches the cranial crests behind the eyes.
Wish to see better pics; but appears yours is an American Toad or Anaxyrus americanus.
