ICK! I am doggie walking in South Florida myself and I know the grossest creatures pop out of nowhere!!!
Yesterday, we were walking along our normal route and all of a sudden a gargantuan iguana/ lizard/ reptile thing was standing in front of us. I screamed - Louis, my Cavalier was wagging his tail, dying to make friends and Ella Bean (who is about the same size as the reptile) stood perfectly still, as if she was trying to disappear. She was not moving. Her little feet were dug into the cement and I had to lift her to continue home.
Picking her up, while keeping Louis from meeting the reptile, while watching the reptile to ensure it didn't attack (do they do that?) was a disaster. This was during the DAY. South Florida just isn't safe
