If you want to learn more about natural pet health and wellness, you’re in the right place.

1. Broccoli Sprouts

A Powerful Detox Food for Dogs

These little broccoli sprouts are one of the most powerful natural foods you can add to your dog’s diet.

They contain sulforaphane, which is one of the most studied natural detoxifiers we know. It helps the liver remove toxins that build up in your dog’s body over time. That includes plastics, pesticides, flea and tick chemicals, and herbicides like Roundup.

Sulforaphane also increases levels of glutathione, the body’s master antioxidant. This matters for liver health, cancer prevention, and slowing cellular aging.

Dose: About 1 tablespoon per 20 pounds of body weight daily.
Tip: Mix it into food. Most dogs will not eat it on its own.

2. Cranberries

Support the Urinary Tract and Reduce Inflammation

Cranberries are an inexpensive nutritional powerhouse.

They are rich in antioxidants and polyphenols, especially anthocyanins. These compounds help prevent and manage urinary tract infections. They also reduce inflammation and support joint health.

Cranberries are also a natural source of quercetin, one of the most important flavonoids for dogs with allergies.

Dose: About 1 teaspoon per 10 pounds of body weight, twice daily.
Best use: For 7 to 10 days when supporting the urinary tract.

Pro tip: Add a natural sweetener like honey. Manuka honey is ideal. It improves taste and has antibacterial effects that help the bladder.

3. MCT Oil

Brain Health, Seizure Support, and Weight Control

MCT oil is a special fat derived from coconut oil.

It provides an alternative energy source called ketones, which the brain can use efficiently. This is especially helpful for senior dogs, dogs with cognitive dysfunction, and dogs with seizures.

MCT oil is also used in ketogenic diets for dogs with epilepsy and certain cancers.

Start low to avoid diarrhea.

Dose: Start with ½ teaspoon per 20 pounds of body weight daily.

4. Greek Yogurt

Probiotics for Gut, Brain, and Immune Health

Greek yogurt is one of the easiest ways to add beneficial bacteria to your dog’s diet.

A healthy gut microbiome supports digestion, reduces anxiety, improves allergies, and even supports brain health as dogs age. There is a strong gut brain connection in dogs.

Greek yogurt also provides protein and minerals.

Dose: 1 teaspoon per 10 pounds of body weight daily.
Use daily or as needed during digestive upset.

5. Blueberries

Antioxidants That Slow Aging

Blueberries are loaded with antioxidants that reduce free radical damage. Less oxidative damage means healthier cells and slower aging.

They also reduce inflammation and support organ health, especially the liver and kidneys.

Blueberries are easy to feed and most dogs enjoy them.

Dose: 3 to 4 blueberries per 10 pounds of body weight, twice daily.

6. Decaffeinated Green Tea

Dental Health and Cancer Support

Decaffeinated green tea retains beneficial compounds like EGCG without the caffeine.

EGCG has been studied for its anti cancer properties, ability to boost metabolism, and support dental health. Dogs that consume green tea compounds may have less plaque and better oral health.

It is also a natural source of quercetin for dogs with allergies.

Dose: About ¼ cup per 20 pounds of body weight daily.
How to use: Add it directly to your dog’s water.

7. Mackerel

Essential Fatty Acids That Dogs Need

Mackerel is one of the best natural sources of essential fatty acids.

It is low in mercury and extremely rich in EPA and DHA. These fatty acids support joints, skin, ears, brain health, and reduce chronic inflammation.

Just one tablespoon of mackerel provides about 500 mg of essential fatty acids.

Dose: 1 tablespoon daily for a 20 pound dog.

This is one of the most researched nutrients in veterinary medicine, and it makes a real difference.

Final Thoughts

These are simple foods. They are affordable, easy to find, and backed by research.

You do not need expensive supplements to improve your dog’s health. Small changes using real foods can support longevity, brain health, digestion, joints, and the immune system.
