I once gave Monday chopped up carrots for a while when she was being fussy about her food, about 3 years ago.
She passed them okay and her poop came out ORANGE.
Now that she has settled down and is eating her doggy food, I do not give them to her. but it was funny seeing the poop in Technicolor. I also had given her chopped up broccoli.
The uncooked carrots are also supposed to be good for their teeth. But a dog biscuit can do the same thing I guess.
