Blueberries are one of the healthiest treats you can give a dog. They're low in sugar, high in antioxidants, and the perfect bite-size. Fresh or frozen, they're an excellent reward.
Why Blueberries Is Good for Dogs
🧬 Powerful Antioxidants
Rich in anthocyanins and flavonoids that fight cell damage and may reduce cancer risk.
💧 Low Sugar & Calorie
~1 calorie per blueberry — one of the most calorie-efficient dog treats available.
🫀 Vitamin C & K
Supports immune function, wound healing, and bone health.
🦴 High in Fibre
Supports digestive health and healthy gut bacteria.
What to Watch Out For
🍬 Sugar Accumulates
Despite being low-sugar individually, large quantities add up. Don't overfeed.
😮 Choking Risk (small dogs)
For tiny dogs, a single blueberry could be a choking hazard. Halve them if needed.
💩 GI Upset in Quantity
Eating a whole punnet at once can cause loose stools. Keep to appropriate portions.
How Much Can Dogs Eat?
Treats should make up no more than 10% of daily calories.
| Dog Size | Safe Serving | Frequency |
|---|---|---|
| XS < 10 lbs | 2–3 blueberries | Daily |
| Small 10–25 lbs | 4–6 blueberries | Daily |
| Medium 25–60 lbs | 8–10 blueberries | Daily |
| Large 60+ lbs | 15–20 blueberries | Daily |
Treats should be ≤10% of daily calories. One blueberry ≈ 1 calorie.
How to Prepare Safely
- Wash before serving — remove any stems
- Serve fresh, frozen, or thawed — all are fine
- For tiny dogs, cut in half to prevent choking
- Don't give dried blueberries — much higher sugar concentration
- Avoid blueberry-flavored products which may contain xylitol
⚠️ Always check first
Only give plain, fresh blueberries. Never give flavored products, processed versions, or anything with added sugar, salt, garlic, or xylitol.
