YIKES! I didn't know this! I'm going to have to check on this! I let Fenway go after the TONS of frogs near our home. He's never eaten them or biten into one. He just chases them! I always say he's going to get warts but I didn't think they could poison him! I'm such a bad parent! First I let him eat grapes when he was a puppy and then find out they can be deadly and now frogs! My poor baby! I'm so glad somebody posted this!
