Will Dogs Be Harmed If They Eat Hornworms

Question From: Wittmann, Arizona, United States
Q: I've been told its hornworm season here. i live in wittmann az 85361, nw corner phoenix, i asked if they are harmful to dogs if they ate one? these are lime green/black stripe. was told they might become a gray moth. otherwise they go back into the ground.i have no garden plants to speak of palm trees n cactus, stone(gravel) dirt, but 3 big dogs that would probably eat one if they saw it crawling. son just wonder if they would be considered poisonous?
