Preparation
Wash them to remove pesticides, especially store-bought. No added sugar, no blueberry muffins, no jam. Fresh or frozen both work perfectly — frozen ones are fun because they bounce.
Quantity
Small dogs (under 10kg): 3-5 berries. Medium dogs (10-25kg): up to 10. Large dogs (25kg+): a small handful, around 15-20.
Notes
The dark skin can temporarily stain light-coloured fur around the mouth — it washes off. Frozen blueberries can be a choking hazard for tiny breeds, so thaw slightly or squish them first.
Nutritional Benefits
* Loaded with antioxidants that fight free radicals and support cell health
* Vitamin C and Vitamin K for immune support and blood clotting
* Low in calories — only about 1 calorie per berry
* Fibre keeps digestion ticking along nicely
* Phytochemicals may help support brain health in ageing dogs
Safe Varieties
1. Fresh blueberries — wash and serve, couldn't be easier
2. Frozen blueberries — a fun, bouncy, cooling treat
3. Mashed blueberries — mix into food or spread on a lick mat
4. Organic blueberries — less pesticide worry, great if you're growing your own
5. Freeze-dried blueberries — fine as long as there's no added sugar or coating
Feeding Guide
Small dogs (under 10kg): 3-5 berries a day as a treat.
Medium dogs (10-25kg): About 8-10 berries.
Large dogs (25kg+): A small handful, up to 15-20.
Puppies: 2-3 berries, mashed or squished to avoid any choking risk.
Positive Signs
* Happily catches them mid-air or eats from your palm
* Normal digestion with no loose stools
* Good energy levels and a shiny coat over time
* Sniffs them out eagerly during treat time
Negative Signs
* Loose stools or diarrhoea — too many at once, scale it back
* Vomiting — rare, but some dogs don't tolerate them
* Choking or gagging — squish them for small breeds
* Purple staining on fur or your carpet — not harmful, just messy
Preparation Science
Fresh blueberries have the most intact Vitamin C. Freezing preserves most nutrients and actually makes the antioxidants slightly more accessible as the cell walls break down. Cooking destroys some vitamins, so raw or frozen is best.
Enrichment Science
Blueberries are small enough to scatter for foraging games. Sniffing and hunting for food engages your dog's brain and taps into their natural scavenging instincts — 10 minutes of nose work can tire them out like a 30-minute walk.
Play Ideas
Easy: Scatter a few blueberries on the floor and let your dog sniff them out.
Medium: Freeze blueberries into ice cubes with water for a summer puzzle treat.
Hard: Hide blueberries inside a snuffle mat for a proper nose-work challenge.
FAQ
Q: Can dogs eat blueberries every day?
A: Yes, in moderation. A few berries daily is perfectly fine and gives a nice antioxidant boost. Just don't replace meals with them.
Q: Are wild blueberries safe for my dog?
A: Wild blueberries are safe and actually tend to have even more antioxidants. Just make sure you can identify them correctly — some wild berries that look similar are toxic.
Alternatives
* Strawberries — similar antioxidant power but higher in sugar and bigger, so easier to portion
* Raspberries — great alternative but contain trace xylitol, so keep portions very small
* Cranberries — tart and less appealing to most dogs, but good for urinary health
* Blackberries — similar nutrient profile, safe in small amounts
Risks & Disclaimer
Blueberries are one of the safest fruits for dogs. Allergic reactions are extremely rare. Start small, watch for digestive changes, and always wash store-bought berries before serving.
