In this instance, yes! You can feed your dog any color of bell pepper and it will not be toxic to your dog, whether it’s yellow, green, red, or orange.

If you’re feeding your dog bell peppers for nutritional value, red bell peppers are your best option. All bell peppers contain various essential nutrients for both humans and dogs, however, red bell peppers are the ones with the highest levels of vitamins and antioxidants. There are additional health benefits you can find in bell peppers since they are so rich in vitamins. 

All of these antioxidants play an important role in your dog’s healthy immune system. One of those antioxidants known as beta-carotene transforms into vitamin A, and in turn, helps parts of your dog’s body such as their skin, eye, and coat health.  Just be sure to introduce your dog to bell peppers slowly and in moderation just like any other human food. Overeating anything can cause your dog indigestion. Also, be sure to cut them into small pieces to prevent choking and avoid any sort of seasoning. Spicy additives can be harmful to your dog’s stomach as well.
