Human food that dogs can eat:

1. Egg yolk: contains lecithin, calcium, phosphorus, iron and other minerals, and is a good nutritional supplement for dogs.

2. Blueberry. Blueberries are available year-round and make a great snack for dogs while training. Blueberries are rich in phytochemicals and antioxidants, and are also an excellent source of fiber, manganese, and vitamins C and E. A dog weighing 10 pounds should eat 2-4 blueberries as a snack every day. Replacing one of the day's snacks with fresh or frozen blueberries is a great way to increase the antioxidants in your dog's food.

3. Kale. Kale is a dark green cruciferous vegetable that is rich in vitamins, iron and antioxidants. It helps detoxify the liver and also has anti-inflammatory properties. Depending on your dog's weight, add 1-3 tablespoons of chopped or pureed kale to your dog's food daily as a great source of fiber and dietary antioxidants.

4. Fermented milk. Fermented milk drink containing beneficial probiotics to support the immune system. While regular pasteurized milk can be irritating to your dog's gastrointestinal tract, fermented milk is different. One of the best and most cost-effective ways to add healthy bacteria to your pet's diet is to make yogurt from your own milk.

5. Mushrooms. Beneficial mushroom species include: shiitake mushrooms, reishi mushrooms, maitake mushrooms, lion's mane, king trumpet, versicolor versicolor, and brasiliensis mushrooms, which are safe for people and pets.

6. Pumpkin. Fresh pumpkin, whether steamed or cooked, is relatively low in calories and high in soluble fiber, which is good for dogs with gastrointestinal upset.

7. Cauliflower. Cauliflower is good for detoxifying your dog's body. It is rich in beneficial nutrients such as potassium, calcium, protein, and vitamin C, and has anti-inflammatory effects.
