Not for dogs. For humans, yes, but not for dogs. Dogs have the teeth of a carnivore. Omnivores and herbivores have flat teeth for grinding up plant matter - dogs cannot do this.

Carrots have vitamins in them which are good for dogs as well as humans.
The vitamins are only utilized in dogs if the carrots are pureed or pulped. Because their teeth can't break the cell walls of vegetables, they derive no nutrition from them. Pureeing or pulping them will break the cell walls and the dog can then get nutrients from it. However, whole veggies still make great treats!
