Wow, I didn't know about the BUFO toad, that one is gigantic. Reptiles sure grow big down south.
My dog loves to chase the lizards, most the frogs stay hidden in the day when she's outside, and we're usually out with her. I really don't think she'd bite one, but certainly glad to know about that one...would relocate it for sure.
We already deal with Cuban tree frogs and they can get really big. Many years ago I went to take a shower and one was on the wall in my shower, as big as my hand. We have no idea how it got in there as it is far from any outside doors, but husband believes it could have come up through the sewer line....remember the woman who found a snake in her toilet????
