My wife and I live on a lake with a creek behind our home in florida. She is currently pregnant and two nights ago the dog was outside barking while I was working, my wife went outside to check what the commotion was about and I believe this to be a cottonmouth. I relocated it about 6 acres away in the property in another Creek where there are no people, it had no teeth but after consuming the toad, it would open its mouth showing the white inner. I'm pretty positive it is a cotton mouth, just wanted to verify having a pregnant wife and pets. We are used to alligators on the property, rat snakes, turkeys, and the banded water snake, which I almost confused for it till I saw its eyes and scales.
