Carrots are considered a safe and healthy food for dogs. Carrots, which are actually taproots, contain large amounts of beta carotene that are converted to vitamin A upon digestion. This vitamin promotes good eyesight and a healthy coat.
Both garden carrots and wild carrots, also known as Queen Anne's lace, can be healthy dog treats. However, only the taproot should be given to dogs; the rest of the plant contains irritants.
There are also several toxic plants that resemble wild carrots. Carrots are distinguished from their toxic cousins by having tighter flower heads and often a solitary purple flower in the middle, but identifying these plants in the field can be difficult if the flowers have been grazed upon by other animals. Caution should be used when feeding wild carrots to dogs for this reason.
