It can be dangerous to feed human foods to dogs, because many foods can cause significant harm to dogs (and many aren’t great for humans either). Fatty foods cause obesity and inflammation. Foods with high sodium levels, especially smoked foods, can be toxic and cause lethal salt poisoning. Artificial sweeteners irritate a dog’s digestive tract and can cause kidney and liver damage. Proteins, especially animal and dairy products, can cause allergies. However, there are still plenty of treats you can share with your pup.

The 5 human-friendly foods below are also good for dogs:

1. Broccoli

Broccoli is rich in proteins and healthy fiber. Vitamin K promotes bone density and strength to keep your dog active for a longer time. Vitamin C has anti-inflammatory properties that boost a dog’s immune system. Folic acid in this cruciferous vegetable helps to make and maintain healthy cells, especially in pregnant dogs. Many minerals in broccoli, including magnesium, chromium, potassium and sodium, also strengthen a dog’s nervous and immune system.

2. Cucumber

Cucumbers give dogs extra hydration, because they contain a high percentage of water. They are also a rich source of vitamin K, which strengthens the dog’s bones. Vitamin K is also vital for exceptionally active dogs, whose joints are more prone to wear and tear. Additionally, dogs can get a fresher breath by eating cucumber, because it combats harmful bacteria that stay in the mouth and cause bad breath. Low-calorie content also makes cucumbers an incredible choice when a dog needs to lose weight.

3. Carrots

This root vegetable has a high soluble fiber content that promotes “helpful” bacteria in the digestive tract to improve digestion and regular bowel movements. Beta-carotene, a vitamin A found in carrots, contributes to good vision. Beta-carotene is also an antioxidant that helps prevent infections, aging, and cancer. A dog that frequently chews a frozen carrot has cleaner teeth because the hard surface clears plaque buildup. Dogs can eat carrots cooked or raw, but lightly steamed is the best. Carrot intake should be moderate, at 5-10% of the diet, to prevent gas buildup and stomach upsets. Be sure to cut the carrots into small pieces to prevent choking.

4. Peanut butter

Peanut butter is a nutritional dog treat with fiber, protein, and healthy fats. Protein supports a dog’s immune system and healthy muscle buildup, and repairs those muscles when they wear out. Healthy fats in peanuts help maintain healthy skin and relieve dryness and irritation. The presence of niacin (vitamin B3) also helps burn fats and sugars into helpful energy. Homemade or unsalted varieties without additives and added sugar are the safest form of peanut butter to give dogs.

5. Green beans

These beans are a great alternative to traditional biscuits, as the low-calorie content creates a feeling of fullness, helping dogs to lose weight when combined with exercise. Green beans also improve digestion in dogs due to their high fiber content. Additionally, green beans contain plenty of protein, calcium, iron, and vitamins A, B6, C and K. However, to prevent stomach upset, green beans should not be over 10% of your dog’s daily diet.
