As I've been reading about this topic, I was surprised to learn about some other fruits, vegetables and grains that are considered healthy for dogs. Some might even help prevent cancer. In Animal Wellness magazine I read about a beautiful Golden, Shawnee, 14 years old, who was thriving on whole food raw and cooked diet. Here are some other foods that are healthy for your pet:
Apples-- vitamin C and antioxidants.
Blueberries-- contain resveratrol, a natural compound with anti-cancer properties
Pumpkin-- helpful to the digestive tract
Chickpea flour--potassium, iron, folate, copper and magnesium
