Can dogs eat blueberries?

Yes, dogs can eat blueberries. Blueberries are one of the safest fruits you can offer as an occasional treat, low in calories and sugar compared to mango or apple, and packed with antioxidants that support healthy ageing. 

Wash them first, feed them whole or mashed depending on your dog's size, and keep portions small: treats of any kind should stay under 10% of your dog's daily calorie intake. Below, we cover exactly how many to give, which blueberry products are off-limits, and when to be extra careful.

How Many Blueberries Can a Dog Eat?

The right portion depends on your dog's size. Use the table below as a guide, and remember that all treats combined should stay under 10% of daily calories.

Mash or halve blueberries for puppies and small dogs to reduce choking risk.

Are Blueberries Beneficial for Dogs?

Blueberries can be a beneficial addition to your dog's diet for several reasons:

1. Nutrient-rich: Blueberries contain essential nutrients, including vitamins C and K, manganese, and antioxidants. Nutrients like these contribute to overall well-being and enhance the immune system.
   
   
2. Low in calories: Blueberries have a low caloric content, making them an appropriate option for dogs aiming to sustain a healthy weight.
   
   
3. Rich in antioxidants: Antioxidants in blueberries, such as anthocyanins, may help combat oxidative stress and inflammation, contributing to long-term health benefits.
   
   
4. High in fibre: The fibre found in blueberries can assist with digestion and promote a healthy gastrointestinal tract.
   
   

Can Blueberries Harm Dogs?

Usually, blueberries are okay for most dogs. But if your dog has diabetes, has tummy troubles with certain foods, or is on special food for health reasons, it is better not to give them sweet fruits like blueberries. A small risk of choking exists, especially for tiny dogs or if the blueberries are frozen.

Even though blueberries are healthy, too many can upset your dog's stomach, primarily because of the sugar. Organic blueberries are the best choice, but remember to wash them well before sharing them with your dog. Wild blueberries are fine if you find them, but don't let your dog go overboard. And be sure they're real blueberries, not some other wild berries that might be harmful. Always keep an eye out for your dog's health!

If you're worried your dog ate too many blueberries, keep an eye out for signs like not wanting to eat, acting tired or sad, looking uncomfortable, or licking lips a lot or gulping. If you notice any of these, call your vet. If you see more severe symptoms like throwing up, lots of diarrhoea, blood in vomit or stool, or your dog getting weak or collapsing, head to the vet straight away.

How Do You Add Blueberries to Your Dog's Diet?

If you want to have some fun treating your dog with blueberries, here are different ways you can do it:

1. Fresh blueberries: Give your dog a handful of fresh, washed blueberries. Just make sure to remove the stems.
   
   
2. Frozen blueberries: For a cool and crunchy treat, offer your dog some frozen blueberries. A great option on a hot day.
   
   
3. Mashed blueberries: Mash up the blueberries and mix them into your dog's regular food. A simple way to add a burst of fruity flavour.
   
   
4. Dried blueberries: If you have a dehydrator, try making your own dried blueberries. Dried blueberries become chewy and can be a special snack.
   
   
5. Blueberry puree: Get a bit fancy by blending blueberries with other dog-friendly fruits like bananas and strawberries. Combine the blend with a bit of plain, sugar-free, xylitol-free yoghurt or peanut butter. Transfer the mixture into an ice cube tray or fill your dog's KONG toy, then freeze for a cool and delicious treat.
   
   
6. Blueberry cake: If you're feeling adventurous, consider making your dog a DIY blueberry birthday cake. Simple recipes using dog-safe ingredients can create a memorable and delicious treat for your dog.
   
   

Positive Impacts of Blueberries on Dogs

Blueberries can have several positive impacts on dogs:

1. Antioxidant boost: Blueberries are rich in antioxidants, which can aid in counteracting harmful free radicals within the body, promoting overall cellular well-being.
   
   
2. Immune system support: The vitamins and minerals in blueberries, such as vitamin C and manganese, can help maintain a robust immune system, assisting your dog in preventing illnesses.
   
   
3. Healthy skin and coat: Nutrients in blueberries may contribute to skin health and a shiny coat. Antioxidants can assist in combating oxidative stress, which may affect skin conditions.
   
   
4. Improved digestion: Dietary fibre in blueberries can assist in digestion and support a healthy gastrointestinal system, helping regulate bowel movements.
   
   
5. Weight management: Blueberries are a low-calorie treat, making them a healthier option for dogs. Blueberries can be part of a balanced diet, especially for dogs watching their weight.
   
   
6. Cognitive health: Some studies suggest that the antioxidants in blueberries may have cognitive benefits, potentially supporting brain function, which is particularly relevant for ageing dogs.
   
   
7. Eye health: Blueberries contain lutein and zeaxanthin. Antioxidants like these benefit eye health and may reduce the risk of age-related macular degeneration.
   
   
8. Joint health: Anti-inflammatory properties of blueberries might help maintain joint health, offering relief for dogs with arthritis or joint issues.
   
   

Remember to introduce blueberries in moderation and consider your dog's overall diet and health. Always consult your veterinarian, especially if your dog has specific health concerns or dietary restrictions.

Best Practices for Offering Blueberries to Your Dog

When introducing blueberries to your dog's diet, start with small amounts to see how your dog reacts. Always wash the berries thoroughly to remove any pesticides or dirt. You can serve blueberries fresh, frozen, or mashed, depending on your dog's preference. Avoid giving your dog blueberry-flavoured treats that may contain added sugars or artificial ingredients. As with any treat, moderation is key to keeping your dog healthy and happy.

The Power of Antioxidants

Antioxidants work to keep things in balance inside the body. Antioxidants tackle troublemakers called free radicals, which, when too many are around, can lead to health problems like diabetes, heart disease, cancer, and joint issues. However, in the right amounts, free radicals help with essential tasks like supporting the immune system, controlling blood flow, fighting infections, and keeping brains sharp.

Antioxidants act like managers, directing free radicals to stick to the good stuff. Blueberries are one of the richest natural sources for these compounds, but a whole team exists in other foods too. Lean meats like chicken or turkey, refreshing watermelon, nutrient-packed pumpkin, sweet mangoes, and even seafood all contribute.

So, if your dog is not into blueberries, you have a variety of antioxidant-rich foods to choose from, ensuring your dog stays healthy and happy.

Frequently Asked Questions

Are blueberry muffins safe for dogs?

No, not store-bought or home-baked ones made for human consumption. Muffins typically contain sugar, butter, and sometimes chocolate or raisins, all of which are unsuitable for dogs. Stick to plain, washed blueberries instead.

Is blueberry yoghurt safe for dogs?

Only plain, unsweetened yoghurt with no xylitol or added sugar, and only in small amounts if your dog tolerates dairy well. Flavoured or sweetened blueberry yoghurt sold for human consumption should be avoided.

Is blueberry juice safe for dogs?

Avoid commercial blueberry juice. Commercial varieties concentrate the sugar and often contain additives. A few whole or mashed fresh blueberries give the same benefit without the sugar load.

Is blueberry jam safe for dogs?

No. Jam is high in added sugar and sometimes contains xylitol, which is toxic to dogs even in small amounts. Fresh or frozen blueberries are the safer choice.

Can dogs have allergies to blueberries?

True blueberry allergies are rare in dogs, but any new food can cause an individual reaction. Introduce a small amount first and watch for itching, vomiting, or loose stools over the next 24 hours.

Can dogs get sick from eating too many blueberries?

Yes. Eating too many at once can cause loose stools or an upset stomach because of the fibre and natural sugar content. Keep portions proportional to your dog's size and treat blueberries as an occasional addition, not a daily staple.

Do commercial dog foods contain blueberries?

Some do, usually as a minor antioxidant-boosting ingredient rather than a primary one. BLEP's Lamb Blueberry recipe uses real blueberries as a core ingredient alongside lamb and lamb liver. Check the ingredient list if you want this as a feature in your dog's regular food.
