Broccoli, whether served raw or cooked, has a lot of nutritional value for dogs. A raw broccoli floret is an inexpensive healthy treat that takes no preparation time and cooked broccoli can easily be included as part of a meal.
Research has proven that broccoli helps prevent cancer and is valuable in fighting infections. In addition, it is known to help the body metabolize drugs and excrete toxins.
Despite its positive attributes, dog owners should avoid overfeeding broccoli. In large amounts, it can cause gastric irritation. Broccoli should not be more than 10 percent of a dog’s diet. The reason for this is that it contains isothiocyanate, which can be a gastric irritant.
