Did you know some of the healthiest foods for your dog are probably already sitting in your kitchen? 👀
Forget expensive “superfood” powders with fancy labels. Many everyday fruits, vegetables, seeds and oily fish contain powerful nutrients that have been studied for their benefits in dogs.
Adding small amounts of fresh whole foods to your dog’s bowl can support everything from their immune system and joints to brain health and digestion.
Here are 15 science-backed foods worth sharing with your best friend 🐶
1. Blueberries 🫐
Blueberries are one of the most researched superfoods for both people and dogs.
They’re packed with antioxidants called anthocyanins, which help protect cells against oxidative stress. This becomes increasingly important as dogs age.
Potential benefits:
- Supports healthy ageing
- Helps protect the brain
- May reduce inflammation
- Rich in vitamin C and fibre
How to feed: A handful for larger dogs or a few berries for smaller dogs.
2. Sardines 🐟
If I could recommend just one whole food, sardines would probably be it.
They are naturally rich in:
- Omega-3 fatty acids (EPA & DHA)
- Vitamin D
- Calcium (when fed whole)
- Selenium
- High-quality protein
Research consistently shows omega-3 fatty acids support:
- Healthy skin and coat
- Brain development
- Joint health
- Heart health
- Reduced inflammation
Choose sardines in water, without added salt or oil.
3. Broccoli 🥦
Broccoli contains compounds like sulforaphane, which researchers are studying for its antioxidant and anti-inflammatory properties.
It’s also rich in:
- Fibre
- Vitamin C
- Vitamin K
Feed small amounts, as too much may upset the stomach.
4. Pumpkin 🎃
Pumpkin is famous for helping dogs with digestive issues, and for good reason.
Its soluble fibre helps regulate bowel movements, whether your dog has diarrhoea or mild constipation.
It also contains:
- Beta-carotene
- Potassium
- Vitamin A
Always feed plain cooked pumpkin.
5. Carrots 🥕
Crunchy, low in calories and naturally sweet.
Carrots provide:
- Beta-carotene
- Fibre
- Vitamin A
Frozen carrots also make an excellent cooling summer snack.
6. Spinach 🌿
Spinach contains:
- Iron
- Folate
- Magnesium
- Vitamin K
- Antioxidants
A little goes a long way.
Because spinach is high in oxalates, it’s best offered occasionally rather than daily, especially for dogs prone to certain urinary issues.
7. Eggs 🥚
Eggs are among the most complete protein sources available.
They provide:
- Essential amino acids
- Choline for brain function
- Vitamin B12
- Selenium
Cook them before feeding to improve digestibility and avoid the small risk of bacteria.
8. Kefir 🥛
Plain, unsweetened kefir is one of the richest natural probiotic foods.
It may help:
- Support gut bacteria
- Improve digestion
- Strengthen the immune system
Introduce it gradually.
9. Chia Seeds
Tiny seeds with huge nutritional value.
Chia contains:
- Omega-3 fatty acids
- Fibre
- Calcium
- Magnesium
Always soak them before feeding.
10. Turmeric
Curcumin (the active ingredient in turmeric) is one of the world’s most researched natural anti-inflammatory compounds.
Some studies suggest it may support:
- Joint comfort
- Healthy ageing
- Cognitive health
Since curcumin isn’t absorbed very well on its own, it’s often combined with healthy fats and a pinch of black pepper.
Always discuss supplements with your vet if your dog is taking medication.
11. Apples 🍎
Without the seeds or core.
Apples provide:
- Fibre
- Vitamin C
- Hydration
They’re an excellent crunchy snack for most dogs.
12. Mushrooms 🍄
Only feed edible mushrooms bought from the supermarket.
Varieties like shiitake and oyster mushrooms contain beta-glucans, which are being researched for immune support.
Never allow dogs to eat wild mushrooms!
13. Green-Lipped Mussels 🦪
Technically not a “human food” many people eat regularly, but incredibly beneficial.
They’re naturally rich in:
- Omega-3 fatty acids
- Glycosaminoglycans
- Minerals
Studies suggest they may improve mobility and comfort in dogs with arthritis.
14. Watermelon 🍉
Perfect during summer.
Watermelon is:
- Around 92% water
- Rich in lycopene
- Full of vitamins A and C
Remove all seeds and the rind first.
15. Bone Broth 🍲
A simple homemade bone broth can encourage hydration while adding flavour to meals.
Choose a recipe with:
- No onions
- No garlic
- No excessive salt
It’s particularly useful for older dogs or dogs recovering from illness.
Foods That Are Healthy… But Only in Moderation
Even healthy foods should remain additions rather than the main part of your dog’s diet.
Remember:
✔️ Introduce one new food at a time.
✔️ Keep portions appropriate for your dog’s size.
✔️ Avoid added salt, sugar, seasoning and artificial sweeteners.
✔️ Fresh whole foods work best.
Every dog is different, and what suits one may not suit another—especially if they have underlying medical conditions or food sensitivities.
My Favourite Superfoods
If I had to pick just five that I regularly include in my own dogs’ diet, they would be:
🥇 Sardines
🫐 Blueberries
