Can Dogs Eat Blueberries? Expert Pet Nutritionist Input

by Tudor Nikolas on Aug 29, 2025
dog on kitchen countertop with a bowl of blueberries and title Cat dogs eat blueberries?

Well.. in principle YES, dogs can eat blueberries! However this is not such a black & white question. The answer ‘yes’ may not be true for every dog. Each dog breed, with their own qualities may affect the answer to what seems like a simple question.

Let's break down the answer for your dog together, as the Lead Pet Nutritionist here at Fetched.

Benefits of blueberries and bilberries

Blueberries were first titled as a ‘super fruit’ due to their extensive properties such as: natural antioxidant, reducing inflammatory biomarkers, disease risk reductions and cardiovascular health (Source). Bilberries are also another type of blueberry that is usually found in the wild, rather than cultivated. They are most prevalent in Northern European countries or in certain parts of USA. These have even higher amounts of antioxidants and beneficial properties.

Studies have found that these properties are equally visible in humans and animals, proving their importance in dog health and nutrition. Not only that, they also aid in regulating blood sugar and supporting heart and brain health, as well as being low in calories.

Do they get any better? Well, yes, their nutritional composition is abundant. They’re packed with endless:

  • Vitamins and Minerals: including Vitamin C, K E, A and B6, as well as manganese, which support immune, bone and metabolic health
  • Plant compounds and antioxidants: Anthocyanins and Quercetin minimise cardiovascular issues and offers anti-inflammatory and anti-allergy effects.
  • Low in calories, high in fibre : ideal for digestive health and weight management. (Source)


Blueberries Pairing tip **

The prebiotic fibre in blueberries aids in digestive health and encourages good gut bacteria. Pairing a couple of blueberries with our Fetched probiotic blend can amplify digestion and overall gut health while delivering a forceful antioxidant punch. 

If you decide to go for the blueberry or bilberry powder, you can sprinkle this on top of your dog's food bowl or in combination with other food toppers too.

This shows bilberry powder you can buy from supermarkets, that is 100% bilberry with no added chemicals.

 

SO… can my dog eat blueberries?

 

In principle YES !

 

Fresh or frozen blueberries are generally safe and healthy for dogs, however there are certain aspects to avoid when feeding your dog blueberries.

1.NO sweetened or canned blueberries - avoid at all costs! They can be high in sugar or artificial sweeteners and can upset your dogs stomach

2. NO overfeeding - Too many can cause upset stomach, sugar overload or loose stools. These risks can be higher if your dogs gut bacteria are out of balance; another reason why pairing blueberries with a quality probiotic supplement can help support digestion. The same goes true for other foods you can feed your dog, such as watermelon or feta cheese; it’s all about moderation.

As a rule of thumb:

Small dogs: ~2-3 blueberries/day

Medium dogs: ~4-5 blueberries/day

Large dogs: ~6-8 blueberries/day (source)

3. Choking hazard - particularly for small dogs! Try cutting them up or mashing them to avoid accidents

4. Underlying conditions - if your dog has diabetes, or is on blood thinners, I recommend checking with your vet before (no matter how temping the benefits of blueberries are). Blueberries are rather high in sugar and it can worsen the diabetes in some cases.

How to serve blueberries 

As a pet nutritionist, these are my favourite methods

  1. Lick Mat - my dog loves it when I mash blueberries onto the lick mat, sprinkle the Fetched probiotic supplement on top and freeze! Its a great enrichment activity and will keep him busy and stimulated for 30 minutes.
  2. As treats - using fresh or frozen blueberries as treats or during training can create a nutritious and positive reward system
  3. Mix into food - sprinkle a few blueberries or bilberries onto of food as a topper, just as the probiotic supplement or add it to our dog collagen product if you want to improve your dog’s joints, to enhance meal times.
  4. Blueberry or bilberry powder - Sprinkle onto their food to further enhance the taste! 


Most dogs can have them whole, but for the smaller dog sizes you can also cut them down into pieces.

When in doubt, ask your vet !

I encourage dog owners to check with their vet, particularly if your dog has prior health conditions or if you have any particular concerns. Every dog is unique, therefore, a dietary change should be made gradually and controlled in order to maintain safety.

In conclusion... 

  • Blueberries are healthy and beneficial in moderation, offering antioxidants, fibre, and vitamins.
  • Serve fresh or frozen only, mind portions and avoid choking hazards. Avoid processed berries or those in compotes or if any sweeteners or preservatives are added.
  • For dogs whose gut or immune could benefit from a little extra support, a few berries paired with a high quality dog probiotic supplement makes snack time both tasty and nutritious.

Why not try sharing a few blueberries with your dog today, safely, deliciously, and with a touch of Fetched care?

Collagen for Dogs with Hyaluronic Acid and Glucosamine by Fetched
Jen and Luna
Night and day improvement

My 16 year old dog Luna has been having difficulties going out for walks, when she used to be super active. Now although she gets excited initially, this excitement didn't last long because after a few runs she would stop dropping the ball probably because of joint pains. I gave her 4 weeks of this collagen with her evening meal and it was a game changer. I genuinely couldn't believe it. Wish I had discovered it sooner. I know it's pricey so we probably won't be able to give it to her continuously but we'll try our best as it really made a difference.

Helped my aging Lily

I have been giving this collagen daily to Lily for the last 3 months and I can say she’s definitely been more active when taking her out for walks and in the garden. She’s just turned 12 so it probably helps with her aging joints.

Much better after a couple weeks

I've been a recurrent buyer of this collagen for several months now and I can say that it's made a huge difference to my aging german shepherd. Helps him get out and about more.

Some improvement in anxiety after 3 weeks

It's been just over 3 weeks and have been adding this to my dachshund's food bowl daily. He seems to be less anxious around people now so seems to be working slightly.

a solid choice for organic dental care

A solid choice for organic dental care. The spirulina and chlorella seem to add a health boost, though the powder can be a bit clumpy so make sure you seal the container well after every use.

calming powder works wonders

Our German Shepherd used to tear up the house whenever we left him alone. Since starting him on this calming powder, he’s much more settled when we’re away.
